Answer 1

Correct Answer - 7
`{:((i) PCl_(3) + O_(2) rarr POCl_(3),(ii) PCl_(5) + CO_(2) rarr " No reaction "),((iii) PCl_(5) + CH_(3)COOH rarr CH_(3)COCl + POCl_(3) + HCl,(vi) PCl_(5) + H_(3)BO_(3) rarr POCl_(3) + B_(2)O_(3)),((v) PCl_(3) + SO_(2)Cl_(2) rarr PCl_(5) + SO_(2),(vi) P_(4)O_(10) + NaCl rarr POCl_(3) + NaPO_(3)),((vii) PCl_(5) + H_(2)O rarr POCl_(3) + 2HCl,(viii) PCl_(5) + SO_(2) rarr SOCl_(2) + POCl_(3)),((ix) PCl_(3) + SO_(3) rarr POCl_(3) + SO_(2),):}`
