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.

A sample was then prepared containing 14.00 mL of coffee and 8.00 mL of 4.80 ppm Li , and diluted to a 50.00 mL total volume. Th
mafiozo [28]

Answer:

The right answer is "[Na^+]=5.57 \ ppm".

Explanation:

The given values are:

\frac{A_s}{A_{coffee}} =\frac{0.840}{1.000}

According to the question,

The concentration of standard will be:

=  \frac{7.80}{50.00}\times 4.80

=  0.156\times 4.80

=  0.748 \ ppm

Coffee after dilution,

⇒  \frac{A_{coffee}}{C_{coffee}} =F\times \frac{A_s}{C_s}

or,

⇒  C_{coffee}=\frac{A_{coffee}}{A_s}\times \frac{C_s}{F}

On substituting the values, we get

⇒               =\frac{1.000}{0.840}\times \frac{0.748}{1.68}

⇒               =1.191\times 1.3104

⇒               =1.561 \ ppm

hence,

In unknown sample, the concentration of coffee will be:

=  1.561\times \frac{50}{14}

=  \frac{78.05}{14}

=  5.57 \ ppm
