For the molecular fragments given below indicate the multiplicity and relative intensities of the peaks that would be produced by the bold-faced hydrogen atoms in a 1H nmr spectrum (you may assume that the R groups do not contain hydrogen atoms within 3 bonds of the bold-face hydrogen):
(i) CH3Cl;
(ii) R1CH2CH2R2;
(iii) R1CH2CH2R1;
(iv) R1R2CHCH2R3;
(v) R1R2CHCH2CH2R3;
(vi) CH3C6H5.
