`NH_4Cl(s)` is heated in a test tụbe. Vapours are brought in contact with red litmus paper, which changes to blue and then to red. It is because of

A

formation of `NH_3 OH and HCI`

B

formation of `NH_3` and HCI

C

greater diffusion of `NH_3` than HCI

D

greater diffusion of HCl than `N_3`

Text Solution

Verified by Experts

The correct Answer is:
C
On heating, `NH_4 Cl to NH_3 +HCI`
Being basic, `NH_3` turns red litmus blue.

Paragraph An organic compound A(C_(9)H_(6)O_(3)) does not react with aqueous solution of NaHCO_(3) as well as does not change the colour of litmus paper. Aon acid hydrolysis gives B(C_(9) H_(8)O_(4)) as major product whereas A on treatment with one equivalent of methanol in acidic medium gives C(C_(10)H_(10)O_(4)) as the major product (other minor isomer of C is also formed). B on heating with sodalime gives toluene. Answer the following questions based on the above information. The structure of A satisfying above conditions is
