Well according to my understanding there is no such thing as a cell wall. But if they are different then the cell membrane is basically a guard. In order for things to come in and out of the cell, they must pass through the cell membrane. Also, the cell membrane protects the cell from germs and any harmful objects. Hope this helps!

Answer:

The structure for the compound elucidated (4-Ethylbenzoic acid) is attached below.

Explanation:

Degree of Unsaturation = $nC - \frac{nH}{2} +\frac{nO}{2} +1$ (where n = no of moles)

= $9-\frac{10}{2} -\frac{2}{2} +1$

= 9 - 6+1 = 4

⇒ 2 ring. 3 double bonds.

From the 1H NMR data given (peaks labeled A-E)

A. 1.2 (3H, t) ⇒ -CH3

B. 2.6 (2H, q) ⇒ -C=C-H or Aromatic-CH3

C. 7.3 (2H, d) ⇒ Aro.-H

D. 8.0 (2H, d) ⇒ Aro.-H

E. 11.0 (1H, s) ⇒ -COOH
