(D) Statement 1 is False and statement 2 is True.
Statement 1: Methyl chloride has a greater dipole moment than methyl fluoride.
And
Statement 2: Chlorine has greater electron affinity value than fluorine.
Dipole moment = (charge) χ (distance between the charges)
Charge is same for Both Cl and F but Bond Length of Cl-C is > F-C = 1.78 Aoand 1.39Ao respectively.
Dipole moment of methyl chloride is 1.90 and the one of methyl fluoride is 1.85
Electron Affinity of Cl > F . But this is not the reason for Dipole Moment
So, Ans is (B)
