Question

question 7 how many bonds (pairs of electrons) are in ch₂=ch₂? two bonds three bonds four bonds six bonds

Explanation:

Step1: Identify structure of CH₂=CH₂

Ethene has two C atoms double-bonded, each bonded to two H atoms.

Step2: Count bonds

Each C-H is single (1 bond); C=C is double (2 bonds). Total: 4 C-H (4 bonds) + 1 C=C (2 bonds) = 6 bonds.

Answer:

D. Six bonds
