Question

chemistry semester 1 exam on level 25-26
possible points 3.41
how many electrons are involved in the following bonds?
triple bond
double bond
single bond

Explanation:

Step1: Recall Bond Electron Sharing

A covalent bond is formed by sharing electron pairs. A single bond shares 1 pair (2 electrons), double shares 2 pairs (4 electrons), triple shares 3 pairs (6 electrons).

Step2: Match Bonds to Electrons

• Triple bond: 3 electron pairs → \( 3 \times 2 = 6 \) electrons.
• Double bond: 2 electron pairs → \( 2 \times 2 = 4 \) electrons.
• Single bond: 1 electron pair → \( 1 \times 2 = 2 \) electrons.

Answer:

• Triple bond: 6 electrons (3 electron pairs).
• Double bond: 4 electrons (2 electron pairs).
• Single bond: 2 electrons (1 electron pair).
