Complete the statements in COLUMN A with the options in COLUMN B. Write only A or B next to the question numbers (1.1.1 to 1.1.7) in the ANSWER BOOK, for example 1.1.8 B.

Step 1: Test with acidified $K_2Cr_2O_7$ (orange solution), heated.

Primary alcohol (Column A):
Orange solution turns green ($Cr_2O_7^{2-} \to Cr^{3+}$).

Secondary alcohol (Column B):
Orange solution turns green ($Cr_2O_7^{2-} \to Cr^{3+}$).

Tertiary alcohol (Column C):
No colour change (remains orange).

Step 2: Test with Lucas reagent ($ZnCl_2$ + conc. $HCl$), at room temperature.

Primary alcohol (Column A):
No reaction, solution remains clear.

Secondary alcohol (Column B):
White turbidity/ppt. appears after 5–10 min.

Tertiary alcohol (Column C):
White turbidity/ppt. appears immediately.

Step 3: Iodoform test ($I_2$ + $NaOH$).

Primary alcohol (Column A, e.g. $CH_3CH_2OH$):
Yellow ppt. of iodoform + smell of iodoform.

Secondary alcohol (Column B, e.g. $CH_3CH(OH)CH_3$):
Yellow ppt. of iodoform + smell of iodoform.

Tertiary alcohol (Column C, e.g. $(CH_3)_3COH$):
No yellow ppt./no reaction.

Column D: Colour change to green (test 1), no turbidity (test 2), no iodoform (test 3).
Primary alcohol.

Column E: Colour change to green (test 1), turbidity after delay (test 2), iodoform (test 3).
Secondary alcohol.

Column F: No colour change (test 1), immediate turbidity (test 2), no iodoform (test 3).
Tertiary alcohol.
