Coordination Compounds MCQs with answer is included in PDF format for FREE. Thousands of students have been benefited from these Coordination Compounds MCQs. Coordination compounds are the compounds that have a tendency to form coordinate or bond between their ions with metallic ion or free radical ion i.e. it contains central atom bonded with multiple number of ligands. Coordination compounds have less bond energy when compared with covalent bond hence they can be easily broken down to form ions and also by using aqueous solvents these compounds can be easily converted into aqueous solution.

FAQs on Coordination Compounds

What is Speciality of coordination compounds?

Coordination compounds have important roles as industrial catalysts in controlling reactivity, and they are essential in biochemical processes. They are a major feature of the chemistry of over half the elements. Coordination compounds have important roles as industrial catalysts in controlling reactivity, and they are essential in biochemical processes. In many ways, coordination chemistry stands as a parallel to organic chemistry as the study of carbon-based reactive clusters that exhibit properties that are often fundamentally different than extended atomic or molecular orbitals

What are the three importance of coordination compounds?

Coordination compounds are employed in many industrial processes and have many applications in quantitative/qualitative chemical analysis within analytical chemistry. The significance of coordination compounds has importance in biological system, the coordination compounds play a vital role in metallurgy and medicine.

How many questions does a coordination compound have in NEET/JEE?

There is a total of 75 questions from all three subjects and for each subject, 100 marks are allotted. out of 75 questions there have a strong possibility to ask 2 to 3 questions in NEET/JEE from this chapter.

What are the applications of coordination compounds?

Coordination compounds, which are defined as chemical compounds whose molecules consist of three-dimensional arrays of atoms bound together by covalent bonds, are abundant in nature. Basic substances such as proteins, starches, and fats are coordination compounds made up of amino acids. Many vitamins are also coordination compounds, including vitamin B12, hemoglobin, and chlorophyll. All biological membranes–the envelopes surrounding cells–are composed of phospholipids, which are also kinds of coordination compounds. Coordination compounds also include dyes and pigments used in the coloring of fabrics and foods; many plant pigments give fruits their color, for example.

Is Ncert enough for coordination compounds for NEET?

Yes for coordination compounds it is enough for neet . As per my opinion coordination chemistry is very easy . There are not much complicated questions in this part . But I recommend you to go through your book twice or thrice . To be able to do questions easily.
