Markovnikov's rule states that in addition to HX across alkene

Last Updated:

This SSC CGL Chemistry question asks: “Markovnikov's rule states that in addition to HX across alkene” The correct answer is H adds to carbon with more H atoms. Markovnikov's rule: In addition of HX to alkene H attaches to carbon bearing more hydrogen atoms. Chemistry explains the composition, structure, properties and transformations of matter. A reliable answer begins by identifying whether the question concerns atomic structure, chemical bonding, periodicity, stoichiometry, acids and bases, redox chemistry, electrochemistry, organic nomenclature, metallurgy or everyday materials. Formulae and equations must be interpreted rather than memorised without context. Numerical problems require the correct molar mass, unit conversion and significant figures.

AH adds to carbon with more H atoms
BX adds to carbon with more H atoms
CH and X add randomly
DBoth H and X add to same carbon
Correct Answer: H adds to carbon with more H atomsYour Answer: A

Explanation

addition of HX to alkene H attaches to carbon bearing more hydrogen atoms. Option B (“X adds to carbon with more H atoms”) is incorrect because it does not satisfy the chemical formula, reaction, periodic trend, numerical relation, oxidation state or definition required by the question. Option C (“H and X add randomly”) is incorrect because it does not satisfy the chemical formula, reaction, periodic trend, numerical relation, oxidation state or definition required by the question. Option D (“Both H and X add to same carbon”) is incorrect because it does not satisfy the chemical formula, reaction, periodic trend, numerical relation, oxidation state or definition required by the question. Identify the governing formula, definition or reaction and apply it consistently. The answer field, correct index and explanation therefore all identify H adds to carbon with more H atoms. Markovnikov's rule: In addition of HX to alkene H attaches to carbon bearing more hydrogen atoms.

FAQ

SSC CGL Chemistry FAQs

Common questions and clear answers for this topic.

How many chemistry questions typically appear in the SSC CGL exam?

Chemistry usually contributes a handful of questions within the General Awareness section, generally covering basic concepts rather than calculation-heavy problems.

Which chemistry topics are most important for SSC CGL preparation?

Atomic structure, periodic table trends, acids-bases-salts, metals and non-metals, and carbon compounds are the areas that appear most consistently across past papers.

Is NCERT chemistry enough to prepare for SSC CGL?

NCERT textbooks from classes 9 and 10 cover most of the conceptual base needed, though supplementing with general knowledge about everyday chemical compounds helps too.

What is the best way to remember chemical reactions and formulas for SSC CGL?

Linking reactions to real-world examples, like rusting or antacids, makes them easier to recall than memorizing formulas in isolation.

Does the SSC CGL chemistry syllabus overlap with the school board syllabus?

Yes, a large part of the syllabus mirrors class 9 and 10 science, making school-level revision a practical starting point.
