Answer:
1. Proteins
2. Alcohol
3. Unsaturated compounds are very reactive.
4. Butene has 4 carbon atoms and one double bonds attached to it
Explanation:
1. The polymerization of amino acids gives protein.
Polymerization is a process whereby smaller unit molecules of organic compounds combine repeatedly, in a regular fashion to form a larger organic structure or compound.
The smaller units are called monomers while the larger compound formed are called the polymers.
In this case, the smaller units are the amino acids held or linked together by peptide bonds to form a polymer called proteins.
2.
Compounds with functional group of -OH are called alcohols.
Alcohols are also known as alkanols and they belong to a class of organic compounds where -OH functional group is attached to an alkyl group. They have general formula of CₓH₂ₓ₊₁OH where x refers to the number of carbon atom. They're also categorized into primary, secondary and tertiary alcohols based on the type of carbon in the which the functional group (-OH) is attached to.
3.
Unsaturated compounds are very reactive due to the presence of lone pairs of electrons present in them.
4. Butene actually has 4 carbon atoms and several single bonds attached to it.
Butene has a total of 12 bonds and 1π (pi-bond) while several 11σ (sigma bonds) are attached to it.

A curved line or surface cannot be measured by a straight scale, a measuring tape or thread must be used instead.To measure a curved line using a thread, follow the below steps:
Tie a knot at one end of the thread.
Place the thread at the beginning of the line and try to measure a small initial portion of the line which is relatively straight.
Place your thumb at the other end of the measured portion and measure next straighter portion.
Repeat the above step till the end of line is reached. Make a knot at the end of the line.
Now, straighten the thread and measure the length of the two knots on a scale.
The mass number = protons + electrons
Atomic number= protons (and electrons)
You can determine the number of neutrons by subtracting the number of protons from the mass number
- Endothermic reaction means the reactant side takes heat from surrounding and get decomposed i.e ∆H=-ve
- If the equation is exothermic then it means the reactant is happy to decompose .But it's not as it's endothermic
Now
- HgO is Omitted from our solution option.
Hg is a atom so no bonds hence no bond strength occurs.
- O_2 is a molecule and so it's our answer .
