Question

1. match the following structures with their name:

a. b.
h h
h-c-n h-c-sh
h h
h h
c. d.
h h h o
h-c-c-c h-c-o-p-o⁻
h h h o⁻
h h
amine choose
sulhydryl choose
aldehyde choose
phosphate choose

Explanation:

1. Amine functional groups contain a nitrogen atom bonded to hydrogen/carbon atoms, matching structure A.
2. Sulfhydryl (thiol) groups have an -SH group, matching structure B.
3. Aldehyde groups have a -CHO (carbonyl bonded to hydrogen) moiety, matching structure C.
4. Phosphate groups have a central phosphorus atom bonded to oxygen atoms (including negatively charged oxygens), matching structure D.

Answer:

amine: A. $\ce{H3C-NH2}$ (structure A)
sulhydryl: B. $\ce{H3C-SH}$ (structure B)
aldehyde: C. $\ce{H3CH2-CHO}$ (structure C)
phosphate: D. $\ce{H3C-O-PO3^{2-}}$ (structure D)
