Explanation
Correct explanation :- Chlorination of CH4 is free radical reaction and free radicals are obtained in sunlight
Correct A:- gives -1- bromo-1- phenyl ethane
Correct R:- Benzyl cation is more stable than alkyl cation
Correct A:- Gives But-2-ene as a major product
Correct explanation :- Neopentane being symmetrical packs more closely in the crystal lattice than isopentane
R is the correct explanation of A
HI adds to vinyl chloride according to markownikoffis rule.
Vol. of cetane = 60 × (2/3) = 40ml
Vol. of α − methy lnaphthalene 60 × (1/3) = 20 ml
∴ Cetane number of diesel sample = (40/60 × 100 ) = 66.6
More the number of C-atoms having maximum hydrogens, i.e, CH3 groups, greater is the heat of combustion. Thus, the increasing order of heat of combustion is III < IV < I < II, i.e. option (a) is correct.
2R – X + Zn → R – R + ZnX2 (Frankland’s Reaction)
Alkyne with Lindlar`s Catalysist (Pd / BaSO4 ) gives Cis- alkene while with Na / Liq.NH3 (Birch Redaction) gives trans-alkene
