Give the structure of the major product expected from the following reactions:
(a) Reaction of ethanal with methyl-magnesium bromide followed by hydrolysis.
(b) Hydration of But-1-ene in the presence of dilute sulphuric acid.
(c) Reaction of phenol with bromine water.
Draw the structures of major product(s) in each of the following reactions:
Calculate the emf of the following cell:
$$\mathrm{Ni}(\mathrm{~s})+2 \mathrm{Ag}^{+}(0.01 \mathrm{M}) \rightarrow \mathrm{Ni}^{2+}(0.1 \mathrm{M})+2 \mathrm{Ag}(\mathrm{~s})$$
Given that $\mathrm{E}_{\text {cell }}^{\circ}=1.05 \mathrm{~V}, \log 10=1$
Account for the following:
(a) Haloalkanes react with AgCN to form isocyanide as main product.
(b) Allyl chloride shows high reactivity towards $\mathrm{S}_{\mathrm{N}} 1$ reaction.
(c) Haloarenes are extremely less reactive towards nucleophilic substitution reactions.
