Step 1. All four (CH3Cl, CH2Cl2, CHCl3, CCl4) are chloromethanes differing only in how many H are replaced by Cl.

Step 2. The book's own trend states liquid alkyl halide density rises with the number of halogen atoms on the same skeleton, since each added chlorine (much heavier than the H it replaces) adds more mass without much added volume.

Step 3. So density rises in the order CH3Cl (D, 1 Cl) < CH2Cl2 (C, 2 Cl) < CHCl3 (B, 3 Cl) < CCl4 (A, 4 Cl) -- exactly D < C < B < A.

✓Final answer

(a) D < C < B < A
