Chemical formula for calcium pyrophosphate is \(C{a_2}{P_2}{O_7}\) The formula for ferric pyrophosphate will be
1 \(F{e_3}{({P_2}{O_7})_3}\)
2 \(F{e_4}{P_4}{O_{14}}\)
3 \(F{e_4}{({P_2}{O_7})_3}\)
4 \(F{e_3}P{O_4}\)
Explanation:
(c) As the formula of calcium pyrophosphate is \(C{a_2}{P_2}{O_7}\) means valency of pyrophosphate radical is \(-4\) so formula of ferric pyrophosphate is \(F{e_4}{\left( {{P_2}{O_7}} \right)_3}\).

Among the bonds formed by a chlorine atom with atoms of hydrogen, chlorine, sodium and carbon, the strongest bond is formed between
1 \(H - Cl\)
2 \(Cl - Cl\)
3 \(Na - Cl\)
4 \(C - Cl\)
Explanation:
(c) \(M - X\) bond is a strongest bond so between \(Na - Cl\) is a strongest bond.

Which of the following is least soluble
1 \(Be{F_2}\)
2 \(Sr{F_2}\)
3 \(Ca{F_2}\)
4 \(Mg{F_2}\)
Explanation:
(b)The solubility order is :\(Be{F_2} > Mg{F_2} > \)\(Ca{F_2} > Sr{F_2}\) so \(Sr{F_2}\) is least soluble.

Which of the following halides has maximum melting point
1 \(NaCl\)
2 \(NaBr\)
3 \(NaI\)
4 \(NaF\)
Explanation:
(d) \(NaF\) has maximum melting point, melting point decreases of sodium halide with increase in size of halide their bond energy get lower.
