Question

Match the species in column I with corresponding character(s) in Column II.

Answer 1

$\stackrel{\oplus }{C}{H}_3$: has hybridization ${sp}^2$ and because of the + sign is a carbocation.

$\stackrel{\oplus }{C}{H}_5$: is carbonium ion.$N{O}^{\oplus }$: has 10 bonding and 4 anti bonding electrons, bond orde 3.

$O_2$: has hybridization ${sp}^2$ and two unpaired electrons, so paramagnetic.

$N_2$: has 10 bonding and 4 anti bonding electrons, bond order 3.
