The order of bond strength: single < double < triple. Bond LENGTHS go in:

AREVERSE order (triple < double < single)
BAll equal
CRandom
DSame order
Answer & Solution
Correct answer: A. REVERSE order (triple < double < single)
Stronger bonds (more shared electrons) pull atoms closer → SHORTER. **So:** triple bond < double bond < single bond in length. E.g. C≡C (120 pm), C=C (134 pm), C-C (154 pm).
