MCQ (Single Correct Answer)

-1

The correct order of increasing bond length of C $$-$$ H, C $$-$$ O, C $$-$$ C and C$$=$$C is

C $$-$$ H < C$$=$$C < C $$-$$ O < C $$-$$ C

C $$-$$ C < C$$=$$C < C $$-$$ O < C $$-$$ H

C $$-$$ O < C $$-$$ H < C $$-$$ C < C$$=$$C

C $$-$$ H < C $$-$$ O < C $$-$$ C < C$$=$$C
