MCQ
Which alky halide has maximum density?
  • A
    C3​H7​F
  • B
    C2​H5​Cl
  • C
    CH3​Br
  • D
    CH3​I
✓

Answer

  1. CH3​I

Explanation:

CH3​I has the highest molecular weight hence, it is alkyl halide with maximum density.

(Mol. wt. of CH3​I) = (Mol. wt. of C) + 3 × (Mol. wt. of H) + (Mol. wt. of I)

= 12 + ( 3 × 1 ) + 127

= 42
