Question

question in the molecule below, which carbons have bond angles of 180°? select all that apply. 1 2 3 4 5 ch₂chch₂cch select all that apply: 1 2 3 4 5

Explanation:

Step1: Recall bond - angle rules

Carbon atoms with sp - hybridization have bond angles of 180°.

Step2: Analyze each carbon's hybridization

Carbon 1 is $sp^{2}$ - hybridized (double - bonded to another carbon), carbon 2 is $sp^{2}$ - hybridized (double - bonded), carbon 3 is $sp^{3}$ - hybridized (single - bonded to four atoms), carbon 4 is sp - hybridized (triple - bonded to carbon 5), carbon 5 is sp - hybridized (triple - bonded to carbon 4). So, carbons 4 and 5 have bond angles of 180°.

Answer:

4, 5
