Carbon monoxide, CO, is an example of a diatomic molecule, while ammonia and glucose, NH3 and C6H12O6, are examples of POLYATOMIC molecules. 7. Ionic compounds are composed of positively and negatively charge ions held together by strong ELECTROSTATIC attraction.

Similar to a molecular equation, which expresses compounds as molecules, an ionic equation is a chemical equation in which the electrolytes in aqueous solution are expressed as dissociated ions. In a balanced ionic equation, the number and type of atoms are the same on both sides of the reaction arrow.

The key difference between balanced equation and net ionic equation is that balanced equation shows all reactions that took place in a system together whereas net ionic equation only shows the net reaction that occurred after the completion of that particular reaction.

Is Potassium Acetate ( KC2H3O2 ) ionic or Covalent bond ?

CH₃COOK is the potassium acetate chemical formula. Potassium acetate molecular weight is 98.14 g/mol. As clear from the formula, Potassium Acetate is formed by one acetate anion CH₃COO- and one potassium cation K+. Both the ions are bonded by ionic bonds.

Calcium hydroxide consists of an ionic bond between a calcium ion, Ca2+ and a hydroxide ion, OH− . The hydroxide ion itself has a single covalent bond between the oxygen and the hydrogen atoms, and so it is a covalent compound ion.

Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca(OH)2. It is a colorless crystal or white powder and is produced when quicklime (calcium oxide) is mixed or slaked with water….Calcium hydroxide.

(BCl4)- for sure because a chloride ion is coordinated to BCl3. BaCl2 and Ca(NO3)2 are strictly ionic and have no coordinated covalent bonds. TiBr4 is actually coordinated by the bromines and these bonds are more covalent than ionic.

We have four fluorine atoms in the molecule. Each fluorine atom contains an unpaired electron on one of the p-orbitals. Since all the valence electrons on Boron participate in bonding, there will be no lone-pair electrons on Boron. Hence the shape of BF4− will be tetrahedral.

Tetrachloroboronanion. Tetrachloro-Borate(1-

– H = 4 means there are four hybrid orbitals involved in hybridization. – Therefore the hybridization of the boron in BF−4 is sp3 . – So, the correct option is C. Note: The shape of the BF−4 is tetrahedral and in the molecule there are four bond pairs and zero lone pairs are present.

BF4- =Sp3. Tetrahedral. BF3 molecule given below.

Now, BF4- doesnot have any vacant p orbital and therefore it cannot take part in back bonding. …

Answer. BF4 is the molecular formula of boron tetraflouride. Boron tetraflouride has tetrahedral structure. Boron has 3 valence electrons, and each of the four fluorides involves with one electron to each covalent bond.

Hence all the M-F bonds are equal in these molecules. However in SF4 there is sp3d hybridization having two axial and two equitorial S-F bonds. Thus all the bond in SF4 are not equal.

Answer: In (ii), BF4- the bond is not equal. Explanation: (i) In XeF4, the configuration of Xe is sp3d2 which have 2 lone pairs on it. (ii) In BF4-, the boron has 3 electrons which makes the covalent bond with 4 fluorides.

Since two axial P-Cl bonds are repelled by three bond pairs each while three equatorial P-Cl bonds are repelled by two bond pairs each, therefore aixad bonds are longer (240 pm) and hence weaker as compared to more stable equatorial bonds (202 pm). Thus, all the five P-Cl bonds in PCl5 are not equivalent.

Therefore the correct order of bond length is C=C>C=N>C=O.
