What is the first step in acid catalyzed dehydration of alcohol?

Deficiency of which vitamin is responsible for osteomalacia?

The unit for molar conductivity is

Primary Alkyl halide \(C _4 H _9 Br (X)\) reacts with alcoholic KOH to give the compound \((Y)\). Compound \((Y)\) is reacted with HBr to give \((Z)\) which is an isomer of \((X)\). When \((X)\) is reacted with \(Na /\) dry ether, it gives a compound \((T), C _8 H _{18}\), which is different from the compound formed when \(n\)-butyl bromide is reacted with \(Na /\) dry ether. The correct IUPAC name of (T) is:

Under Ganga Action and Yamuna Action plans, it is proposed to

Read the Passage carefully and answer the the questions
Insulin consists of two short polypeptide chains : chain A and chain B, that are linked together by disulphide bridges. The first clinical gene therapy was given in 1990 to a 4-year old girl with adenosine deaminase (ADA) deficiency. This enzyme is crucial for the immune system to function. Recombinant DNA technology, Polymerase Chain Reaction (PCR) and Enzyme Linked Immuno-sorbent Assay (ELISA) are some of the techniques that serve the purpose of early diagnosis of diseases. Transgenic animals that produce useful biological products can be created by the introduction of the portion of DNA (or genes) which codes for a particular product such as human protein (α-1-antitrypsin) used to treat emphysema. Biopiracy is the term used to refer to the use of bio-resources by multinational companies and other organisations without proper authorisation from the countries and people concerned without compensatory payment.
In early diagnosis of disease, the principle of antigen-antibody interaction operates in -
