Preparing the family tree using the following symbol:

According to the given information,

Hence, Q is the grandmother of S.

The correct answer is 1 i.e. propanal.

Concept:

IUPAC nomenclature:

• A systematic method of naming organic compounds.
• Naming is based on their structures.
• It is devised by the International Union of Pure and Applied chemistry.
• Many rules are followed while naming the compounds and it is different for different functional groups.
• The rules are known as IUPAC rules.

Explanation:

• This compound contains 3 carbon atoms, so its parent alkane is propane.
• It also contains an aldehyde group (-CHO-) group which is indicated by using 'al' as suffix or ending.
• So by replacing the last 'e' of butane with 'al', the name becomes propanal.
• Thus, the IUPAC name of the compound CH₃CH₂CHO is propanal.
• The common name of propanal is Propionaldehyde.

​Additional Information

• The chart for priority order and suffix name is given below:

Given expression,

84% of 9600 + 48% of 6900 = ? + 50% of 2000

⇒ (84/100) × 9600 + (48/100) × 6900 = ? + (50/100) × 2000

⇒ 84 × 96 + 48 × 69 = ? + 50 × 20

⇒ 8064 + 3312 = ? + 1000

⇒ 11376 = ? + 1000

⇒ ? = 11376 - 1000 = 10376

Helium is the smallest atom. The energy level of the electrons determine the atom's volume. Electrons have a negative charge and the nucleus is positive since it is made up of protons and neutrons. Helium and Hydrogen have one and two electrons. This means they are in the the first energy sub level which is 1S (It can hold up to two electrons) So if that's all we were to consider, both atoms would be the same size. However, since Helium has more protons and electrons, the electrons have a greater attraction to the nucleus, thus decreasing its volume. So it is wrong to just look at atomic number. Hydrogen is not the smallest atom, it is the second smallest and Helium is the smallest.

Actinides are highly electropositive and reactive metals.

Ionisation isomerism is due to the exchange of groups between the complex ion and the ions outside it, e.g. [Cr(H₂O)₄CI(NO₂)CI] and [Cr(H₂O)₄CI₂]NO₂ show ionisation isomerism. 

1. ELASTOMERS - The polymer chains are held together by the weakest intermoleculer faces. These weak binding forces permit the polymer to be stretched. 
   
2. FIBERS - Fibers have strong intermoleculer forces like hydrogen bonding. These strong forces also lead to close packing of chains and thus impact crystalline nature. 
3. THERMOPLASTICS - They posses intermoleculer forces of attraction intermediate between elastomers and fibers. 
4. THEMOSETTING - They are cross linked & heavily launched.
