Students might wonder why Transition metals have variable oxidation states unlike s and p block elements, there are several reason which are mentioned below;

• Most of the d block elemets have incompletely filled d-orbitals, which allow multiple electrons to be lost in bonding process.
• The energy difference between (n-1)d and ns orbitals is small, so both d and s orbital electrons can participate in bonding.
• They form stable ionic and covalent bonds, adjusting oxidation states according to ligand or reaction conditions.

Students can check more such questions and answers in our NCERT Solution pages, for all NCERT Tesxtbooks.

Yes IPU CET syllabus is largely based on the NCERT

• BTech: Physics, Chemistry and Mathematics from the NCERT books.
• BBA and other management courses: English, General Awareness, Logical Reasoning and Aptitude but may also require additional preparation.
• MCA: Mathematics, Logical Reasoning, and Computer Awareness, with some concepts from NCERT and additional advanced topics.
• However, the exam is not strictly limited to NCERT books. Referring to other competitive exam books can be beneficial.

Hope it helps! 

While NCERT books provide a strong foundation, they might not be sufficient for the AU AIMEE Pharmacy exam, which requires a deeper understanding and application of concepts beyond the basic level covered in NCERT. 

NCERT books are excellent for building a strong conceptual understanding of Physics, Chemistry, and Biology, which are core subjects for the AU AIMEE Pharmacy exam.

However, the AU AIMEE Pharmacy exam often tests your ability to apply these concepts to solve problems and understand complex scenarios, which requires going beyond the basic level of NCERT.
