Question

select basic polar non - polar acidic select

Explanation:

Step1: Analyze top - structure

The top structure has a benzene ring attached to the main chain. Benzene is non - polar, but the presence of the carboxyl group ($-COOH$) and the amino group ($-NH_2$) makes the overall molecule polar. Also, the carboxyl group can release a proton making it acidic.

Step2: Analyze bottom - structure

The bottom structure has an amino group ($-NH_2$) at the end and a guanidino group which is a strong base. The presence of these basic groups makes the molecule basic.

Answer:

For the top structure: Polar, Acidic
For the bottom structure: Basic
