Nucleic Acid is a complex organic substance present in living cells, especially DNA or RNA whose molecules consist of many nucleotides linked in a long chain.
Nucleotide is a compound consisting of a nucleoside linked to a phosphate group. They form the basic structural unit of nucleic acids such as DNA.
<h3>1. what is a typical characteristic of an ionic compound?</h3><h3>Answer:</h3>
Option-D : The ionic compound has a high melting point.
<h3>Explanation:</h3>
Ionic compounds are made up of positive ions called cations and negative ions called as anions. Cations are formed when an atom or group of atoms looses one or more electrons while, anion is formed when an atom or group of atoms gains electrons.
The two opposite ions formed interact through electrostatic interactions and form one of the strongest intramolecular bonding called ionic bonding. It requires very high energy to separate these ions from each other in solid form.
Examples: Melting Point of NaCl = 801 °C
Melting Point of MgCl₂ = 714 °C
Melting Point of CaCO₃ = 825 °C

<h3>2. what is shown by the structural formula of a molecule?</h3><h3>Answer:</h3>
Option-A : The arrangement of bonded atoms.
<h3>Explanation:</h3>
Structural formula is the graphical representation of of a chemical formula in either two dimensional or three dimensional space. It helps in depicting the arrangement of atoms or group of atoms in a compound or molecule.
Examples:
Below the attached figure shows the structural formula of Glucose with Chemical formula C₆H₁₂O₆, Sulfuric Acid with Chemical formula H₂SO₄ and Water with Chemical formula H₂O respectively.
