Among carbon-carbon single, double and triple bonds, the shortest and strongest is the:

Answer: triple bond.

  • A triple bond
  • B double bond
  • C single bond
  • D they are all equal

Correct answer: A. triple bond

Explanation: A triple bond has the greatest number of shared electron pairs, so it is the shortest and strongest, while the single bond is the longest and weakest.

VSEPR theory predicts molecular shape from the number of bonding and lone electron pairs around the central atom.

Concept context

Understand how atoms join to form molecules. Covers ionic and covalent bonding, VSEPR theory, hybridization (sp, sp², sp³), molecular orbital theory, bond polarity, and intermolecular forces like hydrogen bonding.
