Propane has a molecular formula C3H8.
It is of the form CnH2n+2.
where n = number of C atoms. In present case n = 3.
Each carbon atom in propane is sp3 hydribized. Thus, there are 4 hydrid orbital associated with each carbon atom
The central C atom is sigma bonded to two other carbon atoms and two hydrogen atoms.
Such, sp3 hydridized orbitals are spacial orientated at an angle of

, in order to minimize repulsion between the electrons.
Hence, the c—c—c bond angle in propane, c3h8, is closest to
Answer: C. Oxygen Gas
Explanation: When Hydrogen Gas and Oxygen Gas combine together it forms water correct. When you have an excess amount of another it stays neutral because it has no other molecule to react with.
Lipids are made up of long hydrocarbon chains and is not soluble in water.
Hence, Option C is correct answer.
<h3>What is Carbohydrates ? </h3>
Carbohydrate is water soluble macromolecule because they are small polar molecules contains many -OH functional groups that makes it hydrophilic.
<h3>What is Nucleic acid ?</h3>
Nucleic acids are long polymeric chain. They are hydrophilic in nature. Nucleic acid are soluble in water because of their polar nature.
<h3>What is Lipids ? </h3>
Lipids are hydrophobic and they are generally water insoluble because lipids are non polar molecules. Lipids are oily or greasy molecules. Lipids are made up of glycerol molecule. It includes fatty acids.
Thus from the above conclusion we can say that Lipids are made up of long hydrocarbon chains and is not soluble in water.
Hence, Option C is correct answer.
