Answer: 1.0 × 10-14
Explanation:
Pure water, represented as
H2O --> [H+] + [OH -]
undergoes a reversible reaction in which both H+ and OH- are generated.
The equilibrium constant for this reaction, called the water dissociation constant, Kw, is 1.0 × 10-14 at 25 °C.
Answer: Rotation occurs at single bonds that are sigma bonds. Rotational barrier is the amount of activation energy required to covert rotamer to another by rotation that occurs around the sigma bond(C-C single bond). Due to the presence of steric hindrance that is the nonbonding interaction effects the reactivity of ions and molecules, activation energy increases. So the rotational barrier in butenyl cation is high.

<u>Answer:</u>
The correct answer option is C. 3.
<u>Explanation:</u>
We are given the number '5.80' and we are to indicate the number of significant figures in the given measured number.
According to the rules of significant figures, numbers that are non-zero, zeros between any two significant numbers and the ending zeros in the decimal position are categorized as significant figures.
Therefore, the number 5.80 has 3 significant figures in it.
