Question

multiple choice 2 points
which of the following is classified as a vinylic halide?
ch₃ch=chch₂cl
brch₂ch=ch₂
ch₃chchoh
ch₃ch=chcl
ch₃ch₂ch₂ch₂br

Explanation:

Step1: Understand vinylic halide definition

A vinylic halide has a halogen atom bonded to a sp² - hybridized carbon of a carbon - carbon double bond.

Step2: Analyze each compound

• For CH₃CH₂CH₂CH₂Br: The Br is bonded to a sp³ - hybridized carbon (alkane - type carbon), not vinylic.
• For CH₃CH=CHCl: The Cl is bonded to a sp² - hybridized carbon (carbon of the double bond), so it is a vinylic halide.
• For CH₃CHCHOH: No halogen atom, so not a halide.
• For BrCH₂CH=CH₂: The Br is bonded to a sp³ - hybridized carbon (CH₂ group), not vinylic.
• For CH₃CH=CHCH₂Cl: The Cl is bonded to a sp³ - hybridized carbon (CH₂ group), not vinylic.

Answer:

CH₃CH=CHCl
