Correct order of first ionization enthalpy is

Last Updated:

This SSC CGL Chemistry question asks: “Correct order of first ionization enthalpy is” The correct answer is Na Al Mg Si. Correct: Na Al Mg Si. Numerical problems require the correct molar mass, unit conversion and significant figures. Organic compounds are named by choosing the correct parent chain, numbering functional groups and multiple bonds, and applying standard prefixes and suffixes. The correct answer should agree with accepted nomenclature, balanced chemistry and the precise wording of the question.

ANa < Mg < Al < Si
BNa > Mg > Al > Si
CNa < Al < Mg < Si
DNa > Al > Mg > Si
Correct Answer: Na < Al < Mg < SiYour Answer: C

Explanation

The answer field, correct index and explanation therefore all identify Na Al Mg Si. Correct: Na Al Mg Si.

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.
