$C{H_3} - \mathop {\mathop {\mathop {\mathop C\limits^| }\limits^{Cl}  - }\limits_{|\,\,\,\,} }\limits_{OH} C{H_2}CH = CHC{H_3}$

$2NOB{r_{(g)\,}}\, \rightleftharpoons \,2N{O_{(g)}}\, + \,B{r_{2(g)}}$

if ${P_{B{r_2}}}$ is $\frac {P}{4}$ At equilibrium and $P$ is total pressure then calculate $\frac {P}{K_P}.$

$(A)\, n = 5, m_l= + 1$
$(B)\, n =2,  l =1, m_l= -1, m_s = -1/2$
The maximum number of electron$(s)$ in an atom that can have the quantum numbers as given in $(A)$ and $(B)$ are respectively
