s-character & electronegativity,
\(\therefore\)  sp hybrid orbitals are more electronegative among the three.

Weight of an organic compound = 0.24 g
Weight of Mg₂P₂O₇ = 0.66 g = y
\( \% \mathrm{P} =\frac{62}{222} \times \frac{\mathrm{y}}{\mathrm{w}} \times 100 \)
\(=\frac{62}{222} \times \frac{0.66}{0.24} \times 100=76.80 \%\)

(w) = 0.33 g
(c) = 0.397 g
\(\% I=\frac{127}{235} \times \frac{c}{w} \times 100=\frac{127}{235} \times \frac{0.235}{0.40} \times 100=31.75 \%\)

Weight of the organic substance = 0.284 g
Weight of AgCl is = 0.287 g = a
\( \% \mathrm{Cl} =\frac{35.5}{143.5} \times \frac{\mathrm{a}}{\mathrm{w}} \times 100 \)
\(=\frac{35.5}{143.5} \times \frac{0.287}{0.284} \times 100=24.98 \% \)

(w) = 0.16 g
(x) = 0.35 g
\(\% S=\frac{32}{233} \times \frac{x}{\mathrm{w}} \times 100=\frac{32}{233} \times \frac{0.35}{0.16} \times 100=30.04 \%\)

w = 0.2175 g
x = 0.5825 g
\( \% \mathrm{~S} =\frac{32}{233} \times \frac{x}{y} \times 100 \)
\(=\frac{32}{233} \times \frac{0.5825}{0.2175} \times 100 \)
= 36.78%

i) Butan.- I - ol & Butan - 2 -ol are position isomers. - Position isomerism
ii) Butan -I -ol & 2-methyl propan - I - ol are chain isomers - Chainisomerism
iii) Butan -I - ol and I - methoxy propane are functional isomers - Functional isomerism
iv) 1 - methoxy Propane and ethoxy ethane and 2 - methoxy Propane are metamers - Metamerism

(w) = 0.33 g
y = 0.397 g
\(\% \mathrm{P}=\frac{62}{222} \times \frac{\mathrm{y}}{\mathrm{w}} \times 100=\frac{62}{222} \times \frac{0.397}{0.33} \times 100=33.60 \%\)
