Interpretation : The physical properties of the elements in group 14 are to be summarized.
Concept Introduction : Group 14 refers to the second group of elements in the p-block of the periodic table. Additionally known as the carbon group. This group's members include Lead (Pb), Germanium (Ge), Tin (Sn), Silicon (Si), and Carbon (C).
The melting and boiling point of the carbon group falls down the group while the density and metallic character is increased.
The general electronic configuration of group 14 components is
As you move down the carbon group, metallic properties become more prevalent in the elements.
The nonmetal is carbon. Metalloids like silicon and germanium exist. Metals include tin and lead.
Carbon can take the form of an orange-red solid, a hard, transparent solid, a soft, slick grey solid, or a black powder.
Silicon can come in the form of a shiny-gray solid or a brown powder.
Germanium is a solid that is glossy, gray-white, and easily fractured.
There are two types of tin as well. One form is a solid that is silvery-white, and the other is a solid that is shiny gray. Both types are malleable and ductile.
Shiny-gray solid is lead. It is ductile, soft, and malleable.
Densities rise and boiling and melting points fall as one moves along the group.

You should have one paragraph each devoted to MS, HNMR, CNMR and IR. 2) For MS, the differing masses of molecular ions are a popular starting point. Including a unique fragmentation is important, too. 3) For HNMR, CNMR and IR state the peaks that are different and what makes them different (usually the presence or absence of certain groups). See if you can find two differences (in each set of IR, HNMR and CNMR spectra) due to the presence or absence of a functional group. Include peak locations. Alternatively, you can state a shift of a peak due to a change near a given functional group. Including peak locations for shifted peaks, as well as what these peaks are due to. Ideally, your focus should be on not just identifying the differences but explaining them in terms of functional group changes.arrow_forward
