Question

ecdysone is a steroid hormone in insects that is involved in larval molting and metamorphosis. classify the highlighted carbons in ecdysone that are bonded to — oh groups as primary, secondary, tertiary, or quaternary. carbon highlighted in red: select carbon highlighted in blue: select

Explanation:

Step1: Recall carbon - type definitions

A primary carbon is bonded to one other carbon, a secondary carbon to two other carbons, a tertiary carbon to three other carbons, and a quaternary carbon to four other carbons.

Step2: Analyze red - highlighted carbon

The red - highlighted carbon is bonded to three other carbons. So it is a tertiary carbon.

Step3: Analyze blue - highlighted carbon

The blue - highlighted carbon is bonded to two other carbons. So it is a secondary carbon.

Answer:

Carbon highlighted in red: Tertiary carbon
Carbon highlighted in blue: Secondary carbon
