Answer to Problem 27P

Angle (1) and angle (2) both measures 180°C.

Explanation of Solution

The given structure is as follows:

  General, Organic, and Biological Chemistry - 4th edition, Chapter 11, Problem 27P , additional homework tip  2

In the compound, triple bonded carbon is bonded to two other groups. If two groups surround an atom and no lone pair electron are present, the bond angle is 180°C and shape around that carbon is linear. So, angle (1) represents 180°C . Angle (2) also is also 180°C as two groups surround the triple bonded carbon atom.

Answer to Problem 27P

Angle (1) and (2) both measures 120°C.

Explanation of Solution

The compound is as follows:

  General, Organic, and Biological Chemistry - 4th edition, Chapter 11, Problem 27P , additional homework tip  4

In the compound, three groups (hydrogen, carbon and chlorine) surround the double bonded carbon atom. And if three groups present surrounding an atom, the bond angle will be 120°C . Hence, angle (1) and (2) both measures 120°C.

Interpretation Introduction

Answer to Problem 27P

Angle (1) and angle (2) both measures 109.5°C.

Explanation of Solution

Given compound is as follows:

  General, Organic, and Biological Chemistry - 4th edition, Chapter 11, Problem 27P , additional homework tip  6

The carbon atom in the compound is surrounded by four groups (two hydrogen, one carbon and one chlorine). So, the angle between the bonds is 109.5°C . Hence, angle (1) and (2) both measures 109.5°C.
