Question

1. what is the name of this fuctional group? r—o—p(=o)(oh)(oh) (the structure is shown with h-o-p=o, r-o-p, and o-h bonds) options: aldehyde, phosphate group, ketone, hydroxyl

Explanation:

• Aldehyde groups have the structure $\text{R-CHO}$, which does not match the given diagram.
• The given structure has a central phosphorus atom double-bonded to an oxygen, single-bonded to two -OH groups, and single-bonded to an R-O- group, which is the defining structure of a phosphate group.
• Ketone groups have the structure $\text{R-CO-R'}$, which does not match the given diagram.
• Hydroxyl groups are single -OH groups, which does not match the multi-atom given structure.

Answer:

phosphate group
