i think it it covalent
CS2 is a pure covalent compound because it consists of nonmetals (carbon and sulfur) bonded together by sharing electrons. In pure covalent compounds, atoms share electrons to form covalent bonds, rather than transferring electrons as in ionic compounds.
Hydrogen oxide (a.k.a. water) is a polar covalent compound.
I'm not sure what you mean by "purely covalent", since the ionic-vs-covalent distinction is expressed in terms of electronegativity, which can take a range of values (higher values = more ionic). CO is very much a covalent compound though.
A compound can be either covalent or ionic in nature. Covalent compounds involve sharing of electrons between atoms, while ionic compounds involve transfer of electrons from one atom to another, leading to the formation of ions.
Perchloric acid (HClO4) is a molecular compound, not an ionic compound. It is a strong acid that dissociates into ions when dissolved in water, but in its pure form, it exists as discrete molecules held together by covalent bonds.
Nitric acid (HNO3) is a molecular compound. It is composed of covalent bonds between the nitrogen (N), oxygen (O), and hydrogen (H) atoms. In its pure form, nitric acid exists as molecules held together by these covalent bonds, rather than as individual ions like in an ionic compound.
H2O is a covalent compound. As hydrogen has only one electron in its outer most shell and oxygen has six electrons in its last shell. Oxygen needs two, while hydrogen requires only one electron to complete its last octave. So oxygen form two covalent bond with two hydrogen atoms. So, water is a covalent compound, but as oxygen is second most electronegative element in the periodic table so due to its high electronegativity the bond no more remains pure covalent, but converted to polar covalent. Hence, water molecule is a polar covalent compound.
KF is an ionic compound because it is formed between a metal cation (potassium) and a non-metal anion (fluorine), resulting in the transfer of electrons from the metal to the non-metal. This creates a strong electrostatic attraction between the ions, leading to an ionic bond.
Water is a non-ionic molecule composed of two covalently bonded hydrogen atoms and one oxygen atom. It does not dissociate into ions in its pure form.
Gasoline is a covalent compound. It is made up of carbon and hydrogen atoms bonded together through covalent bonds. Gasoline is a complex mixture of hydrocarbons that are nonpolar molecules and do not dissociate into ions in solution.
No NaCl has nearly pure ionic bond
KCl is an ionic compound. The electronegativity of potassium (K) is approximately 0.82. The electronegativity of chlorine (Cl) is approximately 3.16. The difference between these electronegativities is 2.34. This high electronegativity difference is what makes potassium chloride an ionic compound. If the electronegativity difference of two elements is greater than 1.7, it is considered to be an ionic compound. If the difference is between 0.4 and 1.7, the compound is considered to be polar covalent. If the difference is less than 0.4, the compound is considered to be covalent. If the difference is 0 (i.e. the two elements are the same), then the compound is considered to be pure covalent. KCl is ionic because K's electronegativity is 0.82 and Cl's is 3.16. A compound is ionic when the electronegativity on the Pauling Scale is more than 2.1. The difference 2.34, so it is ionic.
