Q.

How to find First IE if carbon in kj/mol

Q.

The correct sequence of increasing covalent character is represented by

1. $LiCl<NaCl<BeC{l}_2$

2. $BeC{l}_2<LiCl<NaCl$

3. $NaCl<LiCl<BeC{l}_2$

4. $BeC{l}_2<NaCl<LiCl$

Q. The correct statements among the following are:

I. Due to greater polarizing power of $L{i}^{+}$, $L{i}_{2}C{O}_3$ is most stable
II. $LiHC{O}_3$ does not exist as solid
III. $NaN{O}_3$ on strong heating gives $NaN{O}_2$ whereas $LiN{O}_3$ will give $L{i}_{2}O$
IV. Sodium & Potassium ions are involved in the transport of sugars and amino acids into the cells
V. $LiF$ is less soluble due to smaller hydration energy of $L{i}^{+}$ ion
