1.	One word answers are givenn for the following, Mark the example which is not correct.A. Alkali metals with lowest melting point- CsB. Alkaline earth metal with higher hydration ethalpy- `Ba^(2+)`C. Alkaline earth metal which imparts brick red colour to the flame-`Ca^(2+)`D. Oxide of alkaline earth metal which is amphoteric in nature -BeO
Answer» Correct Answer - B Hydration enthalpy decreases with increases in ionic size down the group. `Be^(2+) gt Mg^(2+) gt Ca^(2+) gt Sr^(2+) gt Ba^(2+)`
