    Which of the following carbon atoms is likely to possess tetrahedral geometry? \[{{H}_{2}}\overset{4}{\mathop{C}}\,=\overset{3}{\mathop{C}}\,H-\overset{2}{\mathop{C}}\,{{H}_{2}}-\overset{1}{\mathop{C}}\,OOH\]

    A)  1                                            

    B)         2

    C)         3                                            

    D)         4

    Correct Answer: B

    Solution :

    \[\underset{s{{p}^{2}}}{\mathop{{{H}_{2}}\overset{4}{\mathop{C}}\,}}\,=\underset{s{{p}^{2}}}{\mathop{\overset{3}{\mathop{C}}\,H}}\,-\underset{s{{p}^{3}}}{\mathop{\overset{2}{\mathop{C}}\,{{H}_{3}}}}\,-\underset{s{{p}^{2}}}{\overset{\begin{smallmatrix}  O \\  || \end{smallmatrix}}{\mathop{C}}}\,-O-H\] \[s{{p}^{3}}\]hybridized carbon atom is likely to posses tetrahedral geometry.
