Acceptors: COO^- group, OH group

Step-by-step solution

Definition of Concept

Hydrogen bond: A hydrogen bond is an electrostatic attraction that occurs between a hydrogen atom covalently bound to a more electronegative atom or group and another electronegative atom with a lone pair of electrons, known as the hydrogen bond acceptor.

Explain the potential hydrogen bond donors and acceptors in the molecules

(a) Consider the given diagram:

In the given diagram donors and acceptors are:

Donors: NH₂ at C2,NH at 9

Acceptors: O at C6,N at 7,N at 3

Therefore, the donors and acceptors in the molecules are:

Donors: NH₂ at C2,NH at 9

Acceptors: O at C6,N at 7, N at 3

Explain the potential hydrogen bond donors and acceptors in the molecules

(b) Consider the given diagram:

In the given diagram donors and acceptors are:

Donors: NH at 1NH₂ at C4

Acceptors: Oat C2,N at 3

Therefore, the donors and acceptors in the molecules are:

Donors: NH at 1NH₂ at C4

Acceptors: Oat C2,N at 3

Explain the potential hydrogen bond donors and acceptors in the molecules

(c) Consider the given diagram:

In the given diagram donors and acceptors are:

Donors: OH group, NH₃

Acceptors: COO^- group, OH group

Therefore, the donors and acceptors in the molecules are:

Donors: OH group, NH₃

Acceptors: COO^- group, OH group
