Choose the incorrect statement.
Propan-2-amine can be obtained by reacting acetoxime with $\mathrm{Na} / \mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}$
Aniline cannot be prepared by Phthalimide reaction
The decreasing order of basic strength of amines in aqueous solution is Ethanamine > $\mathrm{N}, \mathrm{N}$-Dimethylaniline > Benzenamine
Fluorobenzene cannot be prepared from Benzenediazonium chloride by Sandmeyer's reaction because Fluorination of the Diazonium salt is highly endothermic in nature
The quantity of Ca that can be produced from molten $\mathrm{CaCl}_2$, with the same quantity of electricity (in coulombs) required to produce 4.8 g of Mg from molten $\mathrm{MgCl}_2$ is: [Atomic mass of $\mathrm{Mg}=24 \mathrm{u}$; Atomic mass of $\mathrm{Ca}=40 \mathrm{u}$ ]
5.2 g
6.0 g
8.0 g
4.8 g
Choose the correct reason:
o-hydroxybenzaldehyde is a liquid at room temperature while $p$-hydroxy-benzaldehyde is a high melting solid, because
o-hydroxybenzaldehyde shows only weak Vanderwal's forces of attraction while in $p$ hydroxy benzaldehyde there is strong Vanderwal's forces of attraction in solid state
o-hydroxybenzaldehyde shows association of the molecules while in $p$-hydroxy benzaldehyde there is no association among the molecules
o-hydroxybenzaldehyde shows intramolecular hydrogen bonding while in $p$-hydroxy benzaldehyde there is no intramolecular hydrogen bonding
p-hydroxybenzaldehyde, shows intramolecular hydrogen bonding while in o-hydroxy benzaldehyde there is stronger intermolecular hydrogen bonding
The number of bond pairs and lone pairs of electrons in the molecule $I F_5$ is:
5,1
6,0
4,2
