Concept explainers
Interpretation:
The magnitude of the dipole moment and the atom lies at the negative end of the dipole in a
Concept introduction:
Polar covalent bond involves an unequal sharing of electrons between two bonded atoms; it creates a partial separation of charge and a dipole moment.
Covalent bonds are polar, if there is a difference in electronegativity between the bonded atoms.
Direction of dipole moment in a molecule is can be represented as follows,

Explanation of Solution
The given bond is
The electronegativity of atoms in a bond will be the deciding factor to predict the dipole moment of the bond.
Electronegativities of the atoms in
Electronegativity difference between atoms in the bond is given below:
Thus, the dipole moment is
Electronegativity of carbon is more than hydrogen. Therefore, the negative end of the dipole lies at more electronegative atom carbon.

- The emission data in cps displayed in Table 1 is reported to two decimal places by the chemist. However, the instrument output is shown in Table 2. Table 2. Iron emission from ICP-AES Sample Blank Standard Emission, cps 579.503252562 9308340.13122 Unknown Sample 343.232365741 Did the chemist make the correct choice in how they choose to display the data up in Table 1? Choose the best explanation from the choices below. No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated. Doing so would eliminate significant information. No. Since the instrument calculates 5 decimal places for the standard, all of the values should be limited to the same number. The other decimal places are not significant for the blank and unknown sample. Yes. The way Saman made the standards was limited by the 250-mL volumetric flask. This glassware can report values to 2 decimal places, and this establishes our number of significant figures. Yes.
