Out of `F_3C COOH` and `H_3C COOH` compounds which would you expect to be stronger acid and why?

Of the two bromoderivaties, C_6H_5CH(CH_3)Br and C_6H_5CH(C_6H_5)Br , which one is more reac-tive in SN_1 substiution reactoin and why?

How would you name the following compounds? CH_3CH_2Br

An optically active amide (A)C_5H_(11)NO on acid hydrolysis gives an acid and NH_3 . When (A) is treated with bromide and alkali a compound is obtained which one treatment with nitrous acid gives an optically active alcohol and nitrogen. The alcohol gives positive iodoform test. What is the structure of A and show the reactions involved.

0.01M solution of KCl and BaCl_2 are prepared in water. The freezing points of KCl is found to be -2^@C . What freezing point would you expect for BaCl_2 solution assuming both KCl and BaCl_2 to be completely ionised?

An aromatic compound (A) on treatment wth aqueous ammonia and heating forms a compound (B) which on heating with Br_2 and KOH froms a compound (c) of molecular formula C_6H_7N . Write the structures and IUPAC names of compounds.

Why do HCl, HNO_3 , etc. show acidic characters in aqueous solutions while solutions of compounds like alcohol and glucose do not show acidic character?

Which compound in each of the following pairs will react fast in S_N2 reaction with OH and why? CH_3Br or CH_3I

An organic compound 'A' having molecular formula C_6H_6O gives a characteristic colour with aqeuous FeCI_3 solution. When 'A' is treated with CO_2 and NaOH at 400K under pressure 'B' is obtained. The compound B on acidification gives compound C which react with acetyl chloride to form D which is a popular pain killer. Deduce the structure of A, B, C and D.
