What is the shape of PCl4+?
What is the shape of PCl4+?
tetrahedral
What is the shape of Nof?
The electron dot diagram for NOF is as follows: The N atom has three electron groups on it, two of which are bonded to other atoms. The molecular shape is bent.
What are the 5 types of molecular shape?
The VSEPR theory describes five main shapes of simple molecules: linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral.
What is the hybridization of phosphorus in pcl6?
In PCl5, the hybridisation of P atom is sp3d.
Can phosphorus have 4 bonds?
Phosphorus can form 5 bonds like in the case of phosphate. While nitrogen is known to make a maximum of 4 bonds (3 covalent, 1 dative covalent).
Why is multi bonding not present in phosphorus?
An atom like phosphorus or sulfur which has more than an octet is said to have expanded its valence shell. This can only occur when the valence shell has enough orbitals to accommodate the extra electrons. For example, in the case of phosphorus, the valence shell has a principal quantum number n = 3.
Does 02 have a triple bond?
Oxygen tends not to form triple bonds due to formal charge reasons. If oxygen starts with 6 electrons and forms a triple bond, then it has 2 lone pair electrons.
Why is phosphorus p4 and not p?
The phosphorus is so larger that the p-orbitals which are required to overlapp sideways , are unable to overlapp sufficiently to make a pie bond. And because of catination it can join with its own atoms and make covalent bonds. and thus it makes P4 molecule.
Why can nitrogen have 3 bonds?
Nitrogen atoms will form three covalent bonds (also called triple covalent) between two atoms of nitrogen because each nitrogen atom needs three electrons to fill its outermost shell. The carbon atom has four electrons in its outermost shell and needs four more to fill it.
Why can oxygen only make 2 bonds?
Oxygen can form two single bonds because it has six valent electrons on its outer shell. It is easier for an oxygen atom to accept or share two electrons instead of losing all six to become stable (Remember that stability involves having a filled outer shell.
Can nitrogen have 4 bonds?
Well, Nitrogen forms four bonds, each consisting of two electrons. There are no unshared electron pairs.
Why is the nitrogen triple bond so strong?
Nitrogen forms strong bonds because of its ability to form a triple bond with its self, and other elements. Thus, there is a lot of energy in the compounds of nitrogen. Before 100 years ago, little was known about nitrogen. Now, nitrogen is commonly used to preserve food, and as a fertilizer.
Can nitrogen form 5 bonds?
Nitrogen cannot really form 5 bonds, unless you count 4 covalent bonds and 1 ionic “bond”. Normally a nitrogen atom forms 3 bonds, but when the nitrogen atom has a positive charge, it is deficient in an electron, so it can form an additional fourth covalent bond.
Is N2 stable or unstable?
N+2 is more stable as compared to n-2 as because n-2 has got 2 extra electrons which causes extra interelectronic repulsions due to which n-2 becomes unstable.
How long is a CC bond?
154 pm
Is c oa polar bond?
If a molecule is completely symmetric, then the dipole moment vectors on each molecule will cancel each other out, making the molecule nonpolar. This is a linear molecule and the C=O. bonds are, in fact, polar. The central carbon will have a net positive charge, and the two outer oxygens a net negative charge.
Which compound will contain the most polar bond?
The answer is b) N – H. The quick answer – right from the get-go, since nitrogen is one of the most electronegative elements in the periodic table, the bond it forms with hydrogen will be the most polar out of all those listed.
How do you know which bond is least polar?
(If the difference in electronegativity for the atoms in a bond is greater than 0.4, we consider the bond polar. If the difference in electronegativity is less than 0.4, the bond is essentially nonpolar.) If there are no polar bonds, the molecule is nonpolar.
How do you know which bond is the most polar?
1 Answer. Check the electronegativities of the atoms involved in each bond. The greatest difference in electronegativity will correspond to the most polar bond.
What is the least polar molecule?
C−H bond is least polar as the electronegativity difference between C and H is the least.
Is h2o more polar than h2se?
Water is more polar than hydrogen sulfide because the oxygen atom is more electronegative than the sulfur atom.
Which is stronger H2S or HBr?
FREE Expert Solution Recall that the strengths of binary acids is based on the electronegativity or size of the nonmetal. In this case, we have two strong acids which are HCl and HBr, hence we can conclude that H2S is the weakest acid.
Is H2Se an oxidizing or reducing agent?
Answer. NO, But H2Te is a reducing agent.
Which has higher boiling point H2O or H2S?
Water has a higher boiling point than hydrogen sulphide. The intermolecular attractions between water molecules are stronger than H2S molecules due to hydrogen bonding in H2O due to high electronegativity and small size of oxygen atom.
