MCQ
The $IUPAC$ name of $C{H_3}COCH{(C{H_3})_2}$is
- AIsopropylmethyl ketone
- B$2-$methyl$-3-$butanone
- C$4-$Isopropylmethyl ketone
- ✓$3-$methyl$-2-$butanone
The longest chain is of four carbon. The functional group here is keto group. The numbering will start from left carbon as the functional group should also have the lowest numbering.
The substituent methyl group will be at third carbon. Hence the IUPAC name of this structure is $3$-Methyl-$2$-butanone.

$C _2 H _4( g )+3 O _2( g ) \rightarrow 2 CO _2( g )+2 H _2 O ( l )$ the amount of heat produced as measured in bomb calorimeter is $1406\,kJ\,mol { }^{-1}$ at $300\,K$. The minimum value of $T \Delta S$ needed to reach equilibrium is $(-).......\,kJ$. (Nearest integer) Given : $R =8.3\,JK ^{-1} mol ^{-1}$
$B.E. (H-H) = x_1 ; B.E. (O = O) = x_2$ ;
$B.E. (O -H) = x_3$
Heat of vaporisation of water $= x_4$ then $\Delta {H_f}$ [heat of formation of liquid water] is
