Answer:
C.overlapping p orbitals
Explanation:
The atoms which comprises of single bond is formed by sigma bond. Sigma bond is formed by the internuclear overlapping of the atomic orbitals. They are formed due to the head on overlapping of the atomic orbitals. Since, the bond is symmetrical about the internuclear axis, it can rotate without the breakage of the bond.
On the other hand, double or triple bonds contains one or two pi bonds respectively along with one sigma bond. Pi bonds are formed by the sideways overlapping and thus they are non-symmetrical about the internuclear axis and thus it breaks if the bond is being rotated.
Thus the answer is:- C.overlapping p orbitals
The given statement is true, because the activation energy must be provided in order for the molecule to reach the transition state because it is a high-energy state. Reactant molecules don't stay in the transition state for very long since it is unstable; instead, they move on to the next phase of the chemical reaction right away.
To create a successful transition state (with lower activation energy). Heat, which is the most frequently employed energy source, favours the breakdown of processes and lowers the amount of energy needed when the enzyme attaches to the substrate.
The remainder of the process can be completed once the molecule has taken in enough energy to reach the transition state.

<u>Answer:</u>
For 1: The correct answer is Option D.
For 2: The correct answer is Option A.
<u>Explanation:</u>
Polar molecules are defined as the of molecules, in which two atoms that combine must be of different element and therefore can create a dipole. For a dipole, there must be a difference in electronegativity and that is achieved when two atoms of different electronegativity combine. The negative dipole or charge is created on the electronegative atom and positive dipole or charge is created on the electropositive atom.
Thus, the correct answer is option D.
Non-polar molecules are defined as the molecules which are formed when two atoms of same element combine, so that a dipole cannot be created. When there is no dipole, there will be no difference in electronegativity and this is achieved when two atoms of same electronegativities combine.
Thus, the correct answer is A.
