    Optically active polyhydroxy aldehydes
  • B
    Optically active polyhydroxy ketones
  • C
    Optically active polyhydroxy aldehydes or ketones
  • Polyhydroxy aldehydes or ketones which may or may not be optically active

Answer

Correct option: D.
Polyhydroxy aldehydes or ketones which may or may not be optically active
d
sugar may be defined as optically active polyhydroxy aldehydes or ketones . as it contains at least one asymmetrical (chiral) carbon and is, therefore, optically active

The process of breaking down of a compound by passing electric current through it is called:
In a conductometric titration, small volume of titrant of higher concentration is added stepwise to a larger volume of titrate of much lower concentration, and the conductance is measured after each addition.

The limiting ionic conductivity ( $\Lambda 0$ ) values (in $mS m ^2 mol ^{-1}$ ) for different ions in aqueous solutions are given below:

Ions $Ag ^{+}$ $K ^{+}$ $Na ^{+}$ $H ^{+}$ $NO _3^{-}$ $CI ^{-}$ $SO _4^{2-}$ $OH ^{-}$ $CH_3COO ^{-}$
$\Lambda_0$ $6.2$ $7.4$ $5.0$ $35.0$ $7.2$ $7.6$ $16.0$ $19.9$ $4.1$

For different combinations of titrates and titrants given in $List-l$, the graphs of 'conductance' versus 'volume of titrant' are given in $List-II$.

Match each entry in $List-I$ with the appropriate entry in $List-II$ and choose the correct option.

A soft drink was bottled with a partial pressure bf $CO _{2}$ of $3$ bar over the liquid at room temperature. The partial pressure of $CO _{2}$ over the solution approaches a value of 30 bar when $44\, g$ of $CO _{2}$ is dissolved in $1\, kg$ of water at room temperature. The approximate $pH$ of the soft drink is............... $\times 10^{-1}$
