STD 12 - 7. Alcohol, phenol and ethers — NEET STD 11 Science — Question

$A _{( g )} \rightarrow 2 B _{( g )}+ C _{( g )}$

$P _{0}$ be initial pressure of $A$ and $P _{ t }$ the total pressure at time $'t'$. Integrated rate equation is :

$(1)$ $Y$ is diamagnetic in nature while $Z$ is paramagnetic

$(2)$ Both $Y$ and $Z$ are coloured and have tetrahedral shape

$(3)$ In both $Y$ and $Z , \pi$-bonding occurs between $p$-orbitals of oxygen and $d$-orbitals of manganese.

$(4)$ In aqueous acidic solution, $Y$ undergoes disproportionation reaction to give $Z$ and $MnO _2$.
