The correct order of increasing bond length of C–H, C–O, C–C and C=C is
Options
(a) C–C < C=C < C–O < C–H
(b) C–O < C–H < C–C < C=C
(c) C–H < C–O < C–C < C=C
(d) C–H < C=C < C–O < C–C
Correct Answer:
C–H < C=C < C–O < C–C
Explanation:
C–H ; bond length = 0.109 nm
C=C ; bond length = 0.134 nm
C–O ; bond length = 0.143 nm
C–C ; bond length = 0.154 nm
correct order of bond length is
C–H < C=C < C–O < C–C
