Answer:
does
not react with in
dark. Thus, (C = C) absent.
[1]
Thus, is
cyclopentane
Or
(i) If alkyl halides are to be dissolved in water, energy is
required to overcome the attractions between the alkyl halide molecules and
break the hydrogen bonds between water molecules. But very less energy is
released when new attractions are set up between alkyl halides and water molecules
and these are not as strong as the original hydrogen bonds in water. Thus,
alkyl halides are less soluble in water. [1]
(ii) Grignard reagent is decomposed even in very slight
traces of moisture.
Thus, Grignard reagent should be prepared under anhydrous
condition. Solvent is ether. It should be and
alcohol free otherwise Grignard reagent is decomposed. [1]
