⇒ Consider following options to fill the blank space in given paragraph.
All members of carbon family when heated in oxygen form oxides. There are mainly two types of oxides, i.e., monoxide and dioxide of formula MO and MO2 respectively. ____ (P) _______ only exists at high temperature. Oxides in higher oxidation states of elements are generally more acidic than those in lower oxidation states. The dioxides — CO2 & _____ (Q) _______are acidic, whereas _____ (R) ___and PbO2 are amphoteric in nature. Among monoxides, ____ (S) _____ is neutral, ________acidic, whereas SnO and ____(T)_____ are amphoteric.
Answer:
Solution:
(P) 3 (SiO) exists only at high temperatures. Among dioxides, CO₂ and (Q) 4 (SiO₂) are acidic, while (R) 6 (SnO₂) and PbO₂ are amphoteric. Among monoxides, (S) 1 (CO) is neutral, and SnO and (T) 7 (PbO) are amphoteric in nature.
