Question

The chemical formula for 2-chloro pentane is:
$A.CH_{5}H_{5}Cl$
$B.C_{5}H_{11}Cl$
$C.C_{4}H_{9}Cl_{2}$
$D.C_{5}H_{9}Cl$

Answer 1

We'll write about the formula of 2-chloro pentane. There are three basic formulas in chemistry i.e. the formula , the formula , and therefore the molecular formula.

Complete step by step answer: A formula could also be how of presenting information about the chemical proportions of atoms that constitute a selected compound or molecule, using element symbols, numbers, and sometimes also other symbols, like parentheses, dashes, brackets, commas and plus (+) and minus (−) signs. A formula may be a simple representation, in writing, of a three-dimensional molecule that exists. It describes a substance, right right down to the specified atoms which make it up. There are three basic formulas in chemistry i.e. the formula , the formula , and therefore the molecular formula . all of these formulas provide slightly different information about the makeup of a substance, and clues to its three-dimensional shape and therefore the way it'll interact with other molecules, atoms and ions.
$CH_{3}-CH(Cl)-CH_{2}-CH_{2}-CH_{3}$

Hence the correct answer is option B.

Additional information: A formula isn't a chemical name, and it contains no words. Although a formula may imply certain simple chemical structures, it isn't the same as a full chemical formula . Chemical formulae can fully specify the structure of only the sole molecules and chemical substances, and are generally more limited in power than are chemical names and structural formulae.

Note: Chemical formulae don't have the complete power of structural formulae to point out chemical relationships between atoms, they're sufficient to stay track of numbers of atoms and numbers of electrical charges in chemical reactions, thus balancing chemical equations so as that these equations are often utilized in chemical problems involving conservation of atoms, and conservation of electrical charge.
