Reason:-magnesium chloride is a good conductor of electricity in in molten state

a Both assertion and reason are correct statements and reason is the correct explanation of of the assertion

b Both assertion and reason are correct statements but reason is not the correct explanation of assertion

c Assertion is correct but reason is wrong statement

d Assertion is wrong but reason is correct statement

e both assertion and reason are wrong statement​

Answer 1

Explanation:

b Both assertion and reason are correct statements but reason is not the correct explanation of assertion

Answer 2

Magnesium chloride is an ionic compound. It is a good conductor of electricity in the molten state. Therefore, the assertion is wrong but the reason is a correct statement. Thus, option (d) is correct.

Explanation:

• Magnesium chloride is an ionic compound. It is formed by the transfer of electrons from magnesium to chlorine.
• Magnesium loses two electrons to form an ionic bond with two chlorine atoms while the two chlorine atoms gain one electron each.
• The reaction can be given as: $\[M{g^{2 + }} + 2C{l^ - } \to MgC{l_2}\]$
• Magnesium chloride does not conduct electricity in solid state.
• However, in the molten state of magnesium chloride, the ions are free to move. Therefore, it conducts electricity in the molten state.
