Explanation:
Answer:
a Oxygen being small in size, highly electronegative, and non-availability of valence electrons in d orbital oxygen shows anomalous behavior. Oxygen is diatomic whereas others are polyatomic. Oxygen is a gas while others are solid. Oxygen is paramagnetic while others are diamagnetic
Oxygen group element, also called chalcogen, any of the six chemical elements making up Group 16 (VIa) of the periodic classification—namely, oxygen (O), sulfur (S), selenium (Se), tellurium (Te), polonium (Po), and livermorium (Lv).
b. Thus, the reaction appears to be first order, but it is actually of second order that's why known as pseudo first order reaction. So, concentration of water can be approximated as constant as its concentration doesn't change a lot during the reaction. thus, hydrolysis of cane sugar is pseudo first order reaction.
