Propene on hydroboration and oxidation produces
- ✓$CH_3CH_2CH_2OH$
- B$CH_3CHOHCH_3$
- C$CH_3CHOHCH_2OH$
- D$CH_3CH_2CHO$
$3C{H_3} - CH = C{H_2} + B{H_3}\,\xrightarrow{{{\text{(Hydroboration)}}}}$ ${(C{H_3}C{H_2}C{H_2})_3}B$ $\xrightarrow[{{\text{(Oxidation)}}}]{{{H_2}{O_2}/O{H^ - }}}$ ${\text{3 C}}{{\text{H}}_3}{\text{C}}{{\text{H}}_2}{\text{C}}{{\text{H}}_2}{\text{OH}}$

$A.$ Surface tension is the outcome of equal attractive and repulsion forces acting on the liquid molecule in bulk.
$B.$ Surface tension is due to uneven forces acting on the molecules present on the surface.
$C.$ The molecule in the bulk can never come to the liquid surface.
$D.$ The molecules on the surface are responsible for vapour pressure if the system is a closed system.
