Consider following compounds:
\( \begin{array}{llll}\text { (I) } \mathrm{H}_{3} \mathrm{X}-\mathrm{NCS} & \text { (II) } \mathrm{H}_{3} \mathrm{Y}-\mathrm{NCS} & \text { (III) }\left(\mathrm{H}_{3} \mathrm{X}\right)_{2} \mathrm{O} & \text { (IV) }\left(\mathrm{H}_{3} Y\right)_{2} \mathrm{O}\end{array} \)
The incorrect statement regarding given compound is :
(a) IF \( Y \) is carbon in compounds (II) and (IV), then both are bent
(b) If \( X \) is silicon in compounds (I) and (III), then both are linear
(c) If \( X \) is carbon and \( Y \) is silicon then compound (I) is more basic than compound (II)
(d) If \( X \) is silicon and \( Y \) is carbon then \( X-\hat{O}-X \) bond angle compounds (III) is greater than
\( Y-\hat{\mathrm{O}}-Y \) bond angle in compounds (IV)
