Isomers of hydrocarbons have the same _______formula but different ____formula.
Misha Larkins [42]

Answer:

Isomers of hydrocarbons have the <u>molecular</u> formula but <u>structural</u> formula.

Explanation:

Molecules with the same structural formula, but different molecular geometries (spatial arrangement) are called isomers. These differences in the arrangement of the various atoms confer certain differences in chemical properties to the resulting hydrocarbons, even though their chemical composition is the same. There are two types of isomers:

Structural isomers: Here, each atom are connected or bonded in different ways, hence structural isomers may contain different functional groups or pattern of bonding. structural isomers are further divided into: chain, position, and functional group isomers.

Stereoisomers: Here, the connections of the atoms are the same, but the difference is in their orientation in space

The molar absorptivity of Beta-carotene at 490 nm is 1.36 x 105 M-1cm-1. What is the concentration of a solution of Beta-caroten
finlep [7]

Answer:

The correct answer to the following question will be Option E (1.0 x 10⁻³ M).

Explanation:

The given values are:

A\lambda =140

\varepsilon=1.36\times 10^5 \ M \ {cm^{-1}}

L = 1 \ cm

As we know,

⇒  A\lambda=\varepsilon CL

On putting the given values in the above formula, we get

⇒  140=1.36\times 10^5\times C\times 1

⇒  C=\frac{140}{1.36\times 10^5}

⇒  C=102.9\times 10^{-5} \ M

So that option E is the right answer.
