How many covalent bonds are present in CHCl3 molecules?

Give an example of a covalent liquid.

The electronic configuration of a hydride ion (H-) is like the electronic configuration of the atom of which element? [1] OR Draw the Lewis dot diagram of H2 molecule. [1]

(c) Sodium fluoride Explanation: Sodium fluoride (NaF) is an ionic compound, meaning it exists as a lattice of ions rather than discrete molecules. In contrast, sugar, glucose, and hydrogen chloride can form molecular structures.

For which of the following ionic compounds no ion has octet? (a) LiH (b) CaO (c) NaCl (d) MgCl2

Why is the formula weight appropriately used instead of the molecular weight in the case of the ionic compounds?

Define the Octet rule. Give two examples of such compounds in which an exception to the Octet rule is observed. OR Write two important differences between ionic and covalent compounds.

How is ionic bond formed in sodium fluoride? (The atomic number of F and Na are 9 and 11 respectively). OR C has 4 electrons in its outermost shell and O has 6 electrons in its outermost shell. Draw the Lewis dot diagram of CO2 molecule.

What type of chemical bond is present in NH3? Draw Lewis electron dot diagram of NH3. (The atomic number of H and N are 1 and 7 respectively)

Show the conventional representation of the H2O molecule by 'dash' sign

Identify the electrovalent and covalent compounds from among the following compounds: LiH, NH₃, KCl, C₂H₆

Give an example of a solid and a liquid covalent compound.
