You can do this as follows:
<?php
$i = 0;
while( have_posts() ) : the_post();
if( $i % 2 == 0 ) :
?>
//html da coluna da esquerda
<?php
else:
?>
//html da coluna da direita
<?php
endif;
$i++;
endwhile;
?>
This way you guarantee that each one will be printed with the respective characteristic of each column.
