Answer 1

Explanation is given in the answer.

al phenol The compounds arte- Benzoic acid meta- amino aceto phenone x insoluble V soluble Nat 203 initial e tad no X X X X - NAOH HOL. After 6 Compound Initial 2 drop initial drop NAOH text-butye phenol x x 12un zoic acies IX - v solid soud. a r meta. ce famed amino acilo phenone X cholesterol NO. 1→ Tert-butyl-phenol, Phenol is slightly acidic, it is not soluble in normal water. It is soluble in Naoh, it farms sodium salt which is souble. Phenol is not hydro- Philic, so it is not soluble in H2O acid so, it is very Benzoic acid is a very uceak NO.2 ress soluble or not soluble in Hao. No.3 Meta - amino acetophenone, has one amine group, which is slightly bousic in natwu. It is soluble in acid, as it forms MHz im prusence of acid. but upon addition of NaOH it becomes soud. NO.4 cholesterol is not so luble in hao, NaHCO3, NaOH or Hel because it is hydrophobic in nature, it contains large hydrocarbon pavet, which is generally not Soluble in water, cholesterol is soluble in acetone, benzer un ethanol, ether etc.
