Question

48. The X X bond length is 1.00 A and C C bond length
is 1.54 A. If electronegativities of 'X' and 'C' are 3.0
and 2.0 respectively, the C-X bond length is likely to
be:
(a) 1.27 Å
(b) 1.18 Å
(c) 1.08 Å
(d) 1.28 Å​

Answer 1

Answer:

Bond length of C-X is 1.18A.

Explanation:

Here,

Bond length of X-X, M= 1A

Bond length of C-C, N= 1.54A

We know, Radius of X-X bond, Rm= M/2 = 0.5A

Radius of C-C bond, Rn= N/2 = 0.77A

So, Bond length of C-X= Rm+Rn-0.09(3-2)=0.5+0.77-0.09= 1.18A

Bond length of C-X is 1.18A

Answer 2

Answer:

Explanation:

Bond length of X-X, M= 1A

Bond length of C-C, N= 1.54A

We know, Radius of X-X bond, Rm= M/2 = 0.5A

Radius of C-C bond, Rn= N/2 = 0.77A

So, Bond length of C-X= Rm+Rn-0.09(3-2)=0.5+0.77-0.09= 1.18A

Bond length of C-X is 1.18A
