Question

Bond length depends upon the size of atoms, hybridisation, resonance, bond order etc. In the following relations. I. Bond length propto size of atoms II. Bond length propto hybridisation (no. of hybrid orbitals) III. Bond length propto bond order Choose the correct option. (A) I and II (B) Only I (C) I and III (D) I, II and III

Statements I and II are correct while the statement III is incorrect. It's correct form is as follows :
Bond length is directly proportional to size of atoms and hybridisation but it is inversely proportional to bond order.
Bond length

\propto \frac{1}{bond order}

Q. Bond length depends upon the size of atoms, hybridisation, resonance, bond order etc. In the following relations.
I. Bond length $\propto$ size of atoms
II. Bond length $\propto$ hybridisation (no. of hybrid orbitals)
III. Bond length $\propto$ bond order
Choose the correct option.

$I$ and $II$

Only $I$

$I$ and $III$

$I, II$ and $III$

Statements I and II are correct while the statement III is incorrect. It's correct form is as follows :
Bond length is directly proportional to size of atoms and hybridisation but it is inversely proportional to bond order.
Bond length $\propto \frac{1}{bond order}$

Q. Bond length depends upon the size of atoms, hybridisation, resonance, bond order etc. In the following relations. I. Bond length ∝ size of atoms II. Bond length ∝ hybridisation (no. of hybrid orbitals) III. Bond length ∝ bond order Choose the correct option.

I and II

Only I

I and III

I,II and III
