Mademuasel [1]

The students have conducted an experiment to check their hypothesis on the thermal conductivity of two metals; Aluminum and steel. The experimental observations have been noted, and the next step based on the scientific procedure is to analyze the data.

Analysis of data suggests that; since the length of wax after 10 min is lower in Al than steel, aluminum is a better thermal conductor.

Compound a is an alkene that was treated with ozone (followed by dms) to yield only 4-heptanone. Draw the major product that is

olga nikolaevna [1]

Alkenes on reacting with ozone results in the formation of ozonide which undergo reductive cleavage in presence of dimethyl sulfide to form carbonyl compounds (aldehyde or ketone). Whereas in presence of hydrogen peroxide it undergoes oxidative cleavage to form carboxylic acids or ketones.

Since, A alkene yields 4-heptanone only on treatment with ozone and DMS thus, it implies that both the chains on the side of the double-bond are similar the product is 4-heptanone that means the double bond is present between the chains at the 4th carbon. Therefore the structure of compound A is 4,5-dipropyloct-4-ene.

The reaction is as shown in the image.

The reaction of A with m-CPBA (meta-perchlorobenzoic acid) followed by aqueous acid $H_3O^{+}$ is shown in the image.

m-CPBA (meta-perchlorobenzoic acid) is a peracid and forms epoxides on reacting with alkenes.

Based on lewis structure analysis, what is the formal charge of the central atom in clf3

MArishka [77]

Formal Charge is calculated as, Lewis structure is attached below,

Formal Charge = [# of valence electrons] - [electrons in lone pairs + 1/2 the number of bonding electrons]

# of valence electrons of Cl = 7

electrons in lone pairs = 4

number of bonding electrons = 6

Formal Charge = [7] - [4 + 6/2]

Formal Charge = [7] - [4 + 3]

Formal Charge = [7] - [7]

Formal Charge = 0

Result:
Formal charge on Cl in ClF₃ is zero.
