An example that shows the way to the general solution:


In[1]:=
temp1={{1},{2},{3},{4}}

Out[1]=
{{1},{2},{3},{4}}

In[2]:=
temp2={{a1},{a2},{a3},{a4}}

Out[2]=
{{a1},{a2},{a3},{a4}}

In[3]:=
Transpose[{temp1,temp2}]

Out[3]=
{{{1},{a1}},{{2},{a2}},{{3},{a3}},{{4},{a4}}}

In[4]:=
Flatten[Transpose[{temp1,temp2}],1]

Out[4]=
{{1},{a1},{2},{a2},{3},{a3},{4},{a4}}
