Law of Radioactive Decay
In this article, we shall study the concept of radioactive decay, decay constant, and half life of radioactive substance. Transformation of radioactive element into another element (radioactive or non-radioactive) is known as radioactive decay or disintegration. In radioactive decay, the nucleus of a radioactive element called parent undergoes a spontaneous change accompanied by the emission […]

Reactions of Alkanes
In last article, we studied preparations of alkenes. In this article, we shall study reactions of alkanes. Reactivity of Alkanes (Less Reactivity): Alkanes are saturated hydrocarbons. They do not contain any functional group. Hence they are less reactive. Under normal conditions, they are not acted upon by concentrated acids, alkalies, oxidising agents etc. Branched-chain alkanes […]
