The central atom is carbon with three hydrogen and one chlorine atom around it. There are no unshared electrons on the carbon so it is tetrahedral.

An easy trick is to count the zeros.
Answer: , , NaOH are all ionic compounds.
Explanation:
It is known that ionic compounds are the compounds in which one atom transfer its valence electrons to another atom. Hence, during this transfer partial opposite charges tend to develop on the combing atoms due to which strong force of attraction exists between the atoms.
An ionic bond is always formed between a metal and a non-metal.
For example, , , NaOH are all ionic compounds.
On the other hand, a compound formed due to sharing of electrons between the combining atoms is known as a covalent compound. Generally, a non-metal with same or different non-metal tends to form a covalent bond.
For example, , etc are all covalent compounds.
Thus, we can conclude that , [tex]CH_3CH_2COONa, NaOH are all ionic compounds.
1. molarity = (moles)/vol in litres
0.5=[(weight/40)*1000]/4
0.5 = weight/16
weight of NaOH = 8 grams
2. weight = 0.45*850*84/100 gms
molecular weight = 85m (not sure abt this)
