Question

xi) Which of the following is the correct order of incr
(a) CH4 < BH; < BeH2 < LiH (b) CH.> BH
(c) BH3 < CHA < LiH<BeH2 (d) BH; >
xii) The strength of oxyacid increases with
(a) polarity of H-X bond
(b) increasing electronegativity of X
(c) number of O atoms
(d) number of H atoms.​

Answer 1

Answer:

The C−H bond is the shortest due to the small size of both atoms & large electronegativity difference.  

The double bonds are shorter than single bonds.

Hence C=C<C−O and C−C

Due to electronegativity difference between C and O

C−O<C−C

∴ Correct order of increasing bond length is :

C−H<C=C<C−O<C−C

Hence, the correct option is B.
