0Consider the following elements with their period number and valence electrons. Elements
Total valence \( e^{-} \)
\( P \)
\( Q \)
\( R \)
\( S \)
\( T \)
\( U \)
cording to
\( \begin{array}{cc}\text { Period number } & \text { Total valence } e^{-} \\ 2 & 4 \\ 2 & 6 \\ 3 & 7 \\ 3 & 3 \\ 3 & 6 \\ 3 & 4\end{array} \)
According to the given informations, answer the following questions :
Choose the incorrect statement :
(a) \( S R_{3} \) is a hypovalent compound
(b) \( \mathrm{UR}_{4} \) can act as a Lewis acid
(c) \( \mathrm{PQ}_{2} \) can not acts as Lewis acid
(d) \( U R_{4}S R_{3} \) : Lewis acidic character
