![]() (i) A and R both are correct, and R is the correct explanation of A. Reason (R) : This is because sodium and chloride ions acquire octet in Assertion (A) : Sodium chloride formed by the action of chlorine gas on ![]() Chemical Bonding and Molecular Structure: Assertion and Reason Questionsġ.(iv) Assertion is wrong statement but reason is correct statement.Ĭorrect Answer: (iv) Assertion is wrong statement but reason is correct statement. Reason (R) : Size of the atom increases on going down the group and theĪdded electron would be farther from the nucleus. (iv) Assertion and reason both are wrong statements.Ĭorrect Answer: (iii) Assertion and reason both are correct statements and reason is correctģ.Assertion (A) : Electron gain enthalpy becomes less negative as we go down (iii) Assertion and reason both are correct statements and reason is correct (ii) Assertion is correct statement but reason is wrong statement. (i) Assertion and reason both are correct statements but reason is not Inner core of electrons than the 2s electrons. The 2p electron hence 2p electron is more shielded by the Reason (R) : The penetration of a 2s electron to the nucleus is more than (iv) Assertion is wrong statement and reason is correct statement.Ĭorrect Answer: (ii) Assertion and reason both are correct statements and reason is correctĢ.Assertion (A) : Boron has a smaller first ionisation enthalpy than beryllium. (iii) Assertion and reason both are wrong statements. (ii) Assertion and reason both are correct statements and reason is correct (i) Assertion is correct statement and reason is wrong statement. Same principal quantum level, the shielding effect of innerĬore of electrons does not increase very much to compensateįor the increased attraction of the electron to the nucleus. Reason (R) : When successive electrons are added to the orbitals in the Solve Assertion and Reason type of questions based on chapter Classification of Elements and Periodicity in Properties from class 11 Chemistry.ġ.Assertion (A) : Generally, ionisation enthalpy increases from left to right in a Classification of Elements and Periodicity in Properties: Assertion and Reason Questions.(ii) Both A and R are true and R is not the correct explanation of A.Ĭorrect Answer: (iii) A is true and R is false. Reason (R) : The path of an electron in an atom is clearly defined. ![]() (ii) Both A and R are true but R is not the explanation of A.Ĭorrect Answer: (ii) Both A and R are true but R is not the explanation of A.ģ.Assertion (A) : It is impossible to determine the exact position and exact Reason (R) : The frequency of radiation emitted by a body goes from a lowerįrequency to higher frequency with an increase in Reason (R) : The chemical properties of an atom are controlled by theĬorrect Answer: (i) Both A and R are true and R is the correct explanation of A.Ģ.Assertion (A) : Black body is an ideal body that emits and absorbs radiations In the following questions, a statement of Assertion (A) followed by a statement of Reason (R) is given.Ĭhoose the correct option out of the choices given below each question.ġ.Assertion (A) : All isotopes of a given element show the same type of chemical Solve Assertion and Reason type of questions based on chapter Structure of Atom from class 11 Chemistry.
