Due to small size atom show strongest back bonding in BF3.
In case of BF3 (2P−2P back bonding) while in BCl3(2P−3P),BBr3(2P−4P) and BI3(2P−5P) back bonding. So extent of back bonding is maximum in (2P−2P)

First and second ionization enthalpies of lithium are $520$ kJ mol$^{-1}$ and $7297$ kJ mol$^{-1}$ respectively. Energy required to convert $3.5$ mg lithium (g) into $\text{Li}^{2+}$(g) $[\text{Li(g)} \rightarrow \text{Li}^{2+}\text{(g)}]$ is _______ kJ mol$^{-1}$. (nearest integer) [Molar mass of Li $= 7$ g mol$^{-1}$]
