GATE CY 2012 Question Paper (12-Feb-2012) (Shift-2)

Consider the E1 reaction of $tert$ -amyl halides from the energy profile given below.

A $20491c{m}^{-1}$ laser line was used to excite oxygen molecules (made of ${}^{16}O$ only) to obtain the rotational Raman spectrum. The resulting rotational Raman spectrum of oxygen molecule has the first Stokes line at $20479c{m}^{-1}$.

Hückel molecular orbital theory can be applied to the allene radical

$C{H}_2=CH-\dot{C}{H}_2$
