Types of Chemical Bonds
The attractive force which has the ability of holding various constituent elements like atoms, ions, molecules, etc. together in different chemical species is termed as a chemical bond. Chemical compounds are dependent on the strength of chemical bonds between its constituents. Stronger the chemical bond, more will be the stability in the chemical compounds. Hence, it can be said that bonding defines the stability of chemical compounds.
Polarizability In Organic Chemistry
Polarizability refers to the ability of an atom/molecule to distort the electron cloud of neighboring species towards itself and the process of distortion of electron cloud is known as polarization.
Coordinate Covalent Bonds
A coordinate covalent bond is also known as a dative bond, which is a type of covalent bond. It is formed between two atoms, where the two electrons required to form the bond come from the same atom resulting in a semi-polar bond. The study of coordinate covalent bond or dative bond is important to know about the special type of bonding that leads to different properties. Since covalent compounds are non-polar whereas coordinate bonds results always in polar compounds due to charge separation.
You are trying to draw some Lewis structures for molecules based on some notes that a friend gave you. Unfortunately, your friend has very bad handwriting, so you can't read everything properly, especially the elemental symbols. You decide to write a shorthand for yourself, and you know that element Q has 4 valence electrons, element R has 5 valence electrons, element T has 6 valence electrons, and element X has 7 valence electrons.
Determine the shape of each of the following molecules from what you know about their valence electrons. Choose the shape for each one from the dropdown menu.
The molecule QX4 has a shape of
The molecule RX3 has a shape of
The molecule QTX2 has a shape of
