Identify the correct statement.
The " D " in $\mathrm{D}(+)$-glucose represents the dextrorotatory nature of Glucose and ( + ) stands for its configuration
During denaturation of Proteins its 3- dimensional structure is destroyed because the primary, secondary and tertiary structures get destroyed due to rise in temperature
Except Glycine and Tryptophan all the other naturally occurring Amino acids are optically active
Glucose gets oxidised to Gluconic acid with $\mathrm{Br}_2(\mathrm{aq})$ which indicates that the carbonyl group in it is an Aldehydic group
$x$ moles of $\mathrm{K}_2 \mathrm{Cr}_2 \mathrm{O}_7$ oxidises 1 mole of ferrous oxalate, in acidic medium. Hence ' $x$ ' is:
2
1.5
1.0
0.5
In the synthesis of $\mathrm{NH}_3$ from $\mathrm{H}_2$ and $\mathrm{N}_2$, if $6 \times 10^{-2}$ mole of hydrogen disappears in 10 minutes, the number of moles of $\mathrm{NH}_3$ formed in 0.3 minutes is:
$4.0 \times 10^{-3}$ moles
$6.0 \times 10^{-3}$ moles
$1.2 \times 10^{-3}$ moles
$1.5 \times 10^{-3}$ moles
The element with the highest third ionisation enthalpy is:
Vanadium( $\mathrm{Z}=23$ )
Manganese ( $\mathrm{Z}=25$ )
Iron ( $\mathrm{Z}=26$ )
Chromium ( $\mathrm{Z}=24$ )
