Hint:We have studied about catenation. Maximum catenation is shown by carbon in the periodic table because of its small size. Butane is an alkane in which four carbon atoms are bonded with single covalent bonds, both Butane and Butane have a molecular formula but the arrangement is different.
Complete answer:We have studied about catenation. Catenation is a process in which the same element forms bonds with itself and forms a chain or a ring molecule. The bond in catenation is covalent. A covalent bond is formed when electrons are shared between atoms. Catenation is shown by elements like sulfur and carbon. Maximum catenation is shown by carbon in the periodic table because of its small size.
Butane is an alkane in which four carbon atoms are bonded with single covalent bonds. Alkane has a molecular formula . When a hydrocarbon has carbon atoms bonded with a double covalent bond, it is called alkene, molecular formula . Similarly, if a hydrocarbon has carbon atoms bonded with a triple covalent bond, it is called alkyne, molecular formula .
Here we are given butane and butane. Both have a molecular formula . Butane is written as:
Here is a prefix that tells us that the chain is continuous and unbranched. Butane is written as:
Here prefix means that all carbon atoms except one are continuous. Notice that the number of carbon and hydrogen atoms are the same in both structures, only the arrangement is different. Such structures are called structural isomers.
Hence, the correct option is .
Note:It is important to know that the name of butane is methylpropane. We know that there are certain steps in naming a hydrocarbon. First, we identify the longest continuous chain and number it consecutively. The number is assigned in such a way that the branched carbon atom gets the lowest possible number.
