Question

Which of the following statements are correct

I. Both $LiCl$ and $MgC{l}_2$ are soluble in ethanol

II. Both $LiCl$ and $MgC{l}_2$ are deliquescent

III. $LiCl$ and $MgC{l}_2$ form hydrates like $LiCl.8H_{2}O$ and $MgC{l}_2.2H_{2}O$

IV. $NaHC{O}_3$ used as fire extinguisher

• A. I, II, III correct
• B. I, II, IV correct
• C. Only III correct
• D. All are correct

Answer 1

The correct option is B

I, II, IV correct

Options I, II and IV are all very accurate. These are all characteristics of the corresponding compounds. As for option III - the compounds $LiCl$ and $MgC{l}_2$ both form hydrates. Only - $LiCl$ forms $LiCl.2H_{2}O$ whereas $MgC{l}_2$ forms $MgC{l}_2.8H_{2}O$
