Question

I-8 EXPERIMENT I: BONDING AND CHEMICAL PROPERTIES PRELAB ASSIGNMENT (continued) 4. Using Pauling's electronegativity (x) values from the Chemistry Data Sheet or the textbook (a) calculate Ay for NaCl and HCl. (1 mark) (b) Assume that a bonding is ionic when the value of Ay 2.0. On the basis of the values of Ax calculated in 4(a), classify the bonding in NaCl and in HCl as ionic, polar covalent, or covalent. (0.5 mark)

Answer 1

Aus) from from Pouling electoonegative scale o 0 Etronegtivity of Na = 0.93 © Elctronegativity of fel = 3.16. 3 Electronegativity of H = 202 le Hetronegativity . solution © electronegativity diffelnce of Nard Ax = Etronegativity of Cl- El. No of Na sx= 3016-0.93 DX= 2.23 © Electronegativity difference of rice. x = son of a - Eon of H. Ox= 3016 - 2.2 = 0.96 e. Eon diffrence in Nald is greater than; So, it is ionic compound. fionic bond). 6. E.N difference of HCd is lower than 2. 80 it å has bond=holau Covalent bond Thank you. May this help you
