To determine which alkane cannot show isomerism, we first need to understand what isomerism is. Isomerism occurs when two or more compounds have the same molecular formula but different structural formulas. 1. Identify the Alkanes Provi

It is high time we acted upon Geoffrey Leeper's advice (Leeper 1948), and used chemical formulas that belong in the twenty-first century, rather than the 1800s. Equally, egregious is the use of terms such as "base ex- change" and "basic cations." Although less common these days, ...
