To prepare for the Bihar Board 12th exam in the science stream and score better marks, students must be familiar with the Bihar Board 12th Chemistry syllabus. Chemistry is a field of study that examines the properties and reactions of the substances that make up matter. It also deals with chemical transformations that result in new compounds.

P-block, D-block, and f-block elements are among the advanced themes in inorganic chemistry, while advanced topics in physical chemistry include electrochemistry and chemical kinetics. Students study different groups of organic substances in organic chemistry, including phenols, ethers, aldehydes, and amines. The curriculum is given a contemporary twist through chapters like Polymers and Chemistry in Everyday Life.
