After the FSc, the MDCAT is conducted for students that want to join the medical field.
As far as the MDCAT preparation is concerned, the students have to prepare the syllabus properly to get a good test score. The students can access the MCQs of chemistry from this platform easily. The MCQs are provided to assist the students so they can solve the questions and prepare accordingly.
MDCAT Chemistry Ch 4 Test
The students sometimes feel anxious about where they can get the chapter-wise MCQs of chemistry. In such cases, they are informed that they can get them from this page. The chapter-wise MCQs are available here for the convenience of the students. The students should go through all the MCQs as it will help them to learn about the type of questions asked in the exam. To get the MCQs of other chapters, keep visiting and get the latest updates.
In this topic,Student should be able to :
a) Characterize electrovalent (ionic) bond as in sodium chloride and calcium oxide.
b) Use the ‘dot-and-cross’ diagrams to explain: i) Covalent bonding, as in hydrogen(H2); oxygen(O2); chlorine(Cl2); hydrogen chloride; carbon dioxide; methane and ethane. ii) Co-ordinate (dative covalent) bonding, as in the formation of the ammonium ion in H3N+– -BF3 and H3O+.
c) Describe the shapes and bond angles in molecules by using the qualitative model of Valence Shell Electron-Pair Repulsion (VSEPR) theory up to 4 pairs of electron including bonded electron pair and lone pair around central atom. d) Describe covalent bonding in terms of orbital overlap, giving and bonds.
e) Explain the shape of and bond angles in ethane, ethene and benzene molecules in terms of and bonds.
f) Describe hydrogen bonding, using ammonia and water as simple examples of molecules containing N-H and O-H groups.
g) Explain the terms bond energy, bond length and bond polarity (electronegativity difference) and use them to compare the nature of covalent bonds i.e. polar and non-polar.
h) Describe intermolecular forces (Van der Waal’s forces), based on permanent and induced dipoles, as in HCl, CHCl3, Halogens and in liquid noble gases.
i) Describe metallic bonding in terms of positive ions surrounded by mobile electrons (sea of electrons).
j) Describe, interpret and/or predict the effect of different types of bonding (ionic bonding; covalent bonding; hydrogen bonding; Van der Waal’s forces and metallic bonding) on the physical properties of substances.
k) Deduce the type of bonding present in a substance from the given information
