Hydroxyproline is a less-common amino acid. (a) Give approximate values for the indicated bond angles. (b) Which are the most polar bonds in the molecule?

(a)

Interpretation Introduction

Interpretation: The bond angle in the given compound should be determined.

Concept Introduction:

Bond length: Bond distance or bond length is the average distance between nuclei of two bonded atoms in a molecule. It is a transferable property of a bond between atoms of fixed types

Bond angle: It is defined as the angle between the orbital contacting bonding electron pair around the central atom in a molecule ion. Bond angle is expressed in degree.

Explanation

The approximate values for the indicated bond angles are determined below:

Angle 1 = 1090 since there are four bond pairs and zero lone pairs around nitrogen atom hence geometry is tetrahedral.

Angle 2 = 1200 since there are three bond pairs and zero lone pairs around carbon atom hence geometry is trigonal planar
