8 0

Answer:

3.45*10^-29

Explanation:

E=hv

h is Planck's constant and v is the frequency (which was given to us)

E=6.626*10^-34 * 5.21*10^4

E=3.452146*10^-29

What is an ionic bond? A. the attraction positive ions have for free electrons B. the force that holds the valence electrons to
Olin [163]
Ionic bond is a type of chemical bond that refers to the bonding of <span>oppositely charged ions (anions and cations) because of attraction and the </span>transfer of valence electron(s) between atoms. Cation is the metal that loses electrons and become a positively charged cation, and anions are the nonmetal that accepts those electrons to become a negatively charged anion.
According this explanation, an ionic bond is:
B. the force that holds the valence electrons to the atom

Cyclic compound A has molecular formula C5H10 and undergoes monochlorination to yield exactly three different constitutional iso
RideAnS [48]

Answer:

A: 1,2-dimethylcyclopropane

Explanation:

The possible cyclic structure with formula C₅H₁₀ are shown in the image.

A is a cyclic compound. On monochlorination, A yields 3 products.

To have 3 products on monochlorination, there should be three different carbon atoms.

Considering structure 1, all carbons have same nature, thus only one product will be formed and thus not a structure of A.

Considering structure 2, there are two different carbon atoms, thus two different structure are formed and thus not a structure of A.

Considering structures 3 and 4 , there are four different carbon atoms, thus four products will be formed and either of them are not a structure of A.

Considering structure 5, there are three different carbon atoms,  thus three different structure are formed and thus the A is structure 5.
