Explanation

Solution

We were asked to find the structure of 4-methyl-2-penten-1-ol. So, we first need to discuss the IUPAC naming rule in brief. Next, we will discuss what is a chemical formula and types of chemical formulas. At last we will be able to write about the structure of 4-methyl-2-penten-1-ol.

Complete step by step answer:
A formulation may be a manner of supplying information about the chemical proportions of atoms that represent a particular compound or molecule, using element symbols, numbers, and every so often also other symbol, like parentheses, dashes, brackets, commas and plus (+) and minus (−) signs and symptoms. A chemical formulation is an easy illustration, in writing, of a 3-dimensional molecule that exists. It describes a substance, right all the way down to the desired atoms which make it up. There are three simple formulas in chemistry i.e. The empirical formula, the molecular system, and the structural formulation. Each one of these formulations barely provide facts about the make-up of a substance, and clues to its 3-dimensional form and the manner it'll have interaction with other molecules, atoms and ions.
According to the IUPAC name of the compound, it has methyl organization connected to the fourth carbon and it has a double bond at the second one position. Also, it has an alcohol group connected to the first carbon atom and overall, there are five carbon atoms in the determined chain.
(CH3)2CH−CH=CH−CH2−OH(CH_{3})_{2}CH-CH=CH-CH_{2}-OH
Hence option 3 is the correct one.

Additional Information:
Although a formula may imply certain simple chemical structures, it's not an equivalent as a full chemical molecular formula. Chemical formulae can fully specify the structure of only molecules and chemical substances, and are generally more limited in power than are chemical names and structural formulae.

Note:
Chemical formulae do no longer have the overall energy of structural formulae to expose chemical relationships between atoms, they are enough to maintain music of numbers of atoms and numbers of electrical fees in chemical reactions, therefore balancing chemical equations simply so those equations are often utilized in chemical problems concerning conservation of atoms, and conservation of electrical fee.
