`R-X+R-ONa rarr ROR + NaX`
D. When a `2^(@)` alcohol is allowed to pass over heated copper at 573 K, dehydrogenation takes place and an keton is formed.
`R-underset(OH)underset(|)(CH)-R' underset(573 K)overset(Cu)rarrR-underset(O)underset(||)(C)-R`
E. On treating phenol with chloroform in the presence of `NaOH`, an aldehydic group is introduced at ortho position of benzene ring

F. Ethanol is prepared by the fermentation of sugars.
`C_(12)H_(22)O_(11)+H_(2)O overset("Invertase")rarrC_(6)H_(12)O_(6)+C_(6)H_(12)O_(6)`
