The strength of bonds by 2s -2s, 2p2p and 2p-2s overlap has the order

A

1s-1s gt 2p -2p gt 2s - 2p gt 2s - 2s

B

2p - 2p gt 2s - 2p gt 2s - 2s gt 1s -1s

C

2s - 2s gt 1s - 1s gt 2s - 2p gt 2p - 2p

D

2s - 2p gt 2s - 2s gt 2p - 2p gt 1s - 1s

Text Solution

Verified by Experts

The correct Answer is:
A
Order of overlapping is
`sigma p - p gt sigmas -p gt sigmas - s, 1s- 1s` bond is stronger because 1s orbital is close to the nucleus.

The strength of bonds by 2s -2s, 2p-2p and 2p-2s overlap has the order

A covalent bond will be formed by the overlapping of atomic orbitals having single electron of opposite spin, according to the overlapping of atomic orbitals the covalent bond may be of two types : (i) Sigma bond (sigma) " " (ii) Pi bond (pi) Sigma bond is stronger bond than the Pi-bond. If atomic orbitals overlap about the nuclear axis then sigma bond is formed but when atomic orbitals overlap sideway then Pi-bond is formed. The strength of bonds formed by 2s-2s,2p-2p and 2p-2s overlap has the order :

The strength of sigma bonds by s-s,p-p.s-p overlap is in the order

Which of the following is correct order of sigma - bond strength ? I. 2s-2s II. 2s-2p III. 2p-2p IV. 3s-3s

An element A has the configuration 1s^(2)2s^(2)//2p^(6)3s^(1) and the elemen B has the configuration 1s^(2)2s^(2)2p^(4) Give the formula of the compound formed. 1s^(2)2s^(2)2p^(6)3s^(1) while the configuration of B is 1s^(2)2s^(2)2p^(5). What type of bond is likely to be formed between them ?
